The "ls-tree" command isn't capable of ending "lines" with anything
except '\n' or '\0', and in the latter case we can avoid calling
write_name_quoted_relative() entirely. Let's do that, less for
optimization and more for clarity, the write_name_quoted_relative()
API itself does much the same thing.

After the the preceding two commits the only user of the
"show_tree_data" struct needed it along with the "options" member,
let's instead fold all of that into a "show_tree_data" struct that
we'll use only for that callback.

As a first step towards being able to turn this code into an API some
day let's change the "static" options in builtin/ls-tree.c into a
"struct ls_tree_options" that can be constructed dynamically without
the help of parse_options().
Because we're now using non-static variables for this we'll need to
clear_pathspec() at the end of cmd_ls_tree(), least various tests
start failing under SANITIZE=leak. The memory leak was already there
before, now it's just being brought to the surface.

As noted in [1] the code that made it in as part of
9c4d58ff2c3 (ls-tree: split up "fast path" callbacks, 2022-03-23) was
a "maybe a good idea, maybe not" RFC-quality patch. I hadn't looked
very carefully at the resulting patterns.
The implementation shared the "struct show_tree_data data", which was
introduced in e81517155e0 (ls-tree: introduce struct "show_tree_data",
2022-03-23) both for use in 455923e0a15 (ls-tree: introduce "--format"
option, 2022-03-23), and because the "fat" callback hadn't been split
up as 9c4d58ff2c3 did.
Now that that's been done we can see that most of what
show_tree_common() was doing could be done lazily by the callbacks
themselves, who in the pre-image were often using an odd mis-match of
their own arguments and those same arguments stuck into the "data"
structure. Let's also have the callers initialize the "type", rather
than grabbing it from the "data" structure afterwards.

When handling "--exec" rebase collects the commands into a struct
string_list, then prepends "exec " to each command creating a multi line
string and finally splits that string back into a list of commands. This
is an artifact of the scripted rebase and the need to support "rebase
--preserve-merges". Now that "--preserve-merges" no-longer exists we can
cleanup the way the argument is handled. There is no need to add the
"exec " prefix to the commands as that is added by todo_list_to_strbuf().

As with the previous patch, using skip_prefix() is more readable and
less error-prone than a raw strncmp(), because it avoids a
manually-computed length. These cases differ from the previous patch
that uses starts_with() because they care about the value after the
matched prefix.
We can convert these to use skip_prefix() by introducing an extra
variable to hold the out-pointer.
Note in the case in ws.c that to get rid of the magic number "9"
completely, we also switch out "len" for recomputing the pointer
difference. These are equivalent because "len" is always "ep - string".

It's more readable to use starts_with() instead of strncmp() to match a
prefix, as the latter requires a manually-computed length, and has the
funny "matching is zero" return value common to cmp functions. This
patch converts several cases which were found with:
git grep 'strncmp(.*, [0-9]*)'
But note that it doesn't convert all such cases. There are several where
the magic length number is repeated elsewhere in the code, like:
/* handle "buf" which isn't NUL-terminated and might be too small */
if (len >= 3 && !strncmp(buf, "foo", 3))
or:
/* exact match for "foo", but within a larger string */
if (end - buf == 3 && !strncmp(buf, "foo", 3))
While it would not produce the wrong outcome to use starts_with() in
these cases, we'd still be left with one instance of "3". We're better
to leave them for now, as the repeated "3" makes it clear that the two
are linked (there may be other refactorings that handle both, but
they're out of scope for this patch).
A few things to note while reading the patch:
- all cases but one are trying to match, and so lose the extra "!".
The case in the first hunk of urlmatch.c is not-matching, and hence
gains a "!".
- the case in remote-fd.c is matching the beginning of "connect foo",
but we never look at str+8 to parse the "foo" part (which would make
this a candidate for skip_prefix(), not starts_with()). This seems
at first glance like a bug, but is a limitation of how remote-fd
works.
- the second hunk in urlmatch.c shows some cases adjacent to other
strncmp() calls that are left. These are of the "exact match within
a larger string" type, as described above.

Fix typos in code comments which repeat various words. Most of the
cases are simple in that they repeat a word that usually cannot be
repeated in a grammatically correct sentence. Just remove the
incorrectly duplicated word in these cases and rewrap text, if needed.
A tricky case is usage of "that that", which is sometimes grammatically
correct. However, an instance of this in "t7527-builtin-fsmonitor.sh"
doesn't need two words "that", because there is only one daemon being
discussed, so replace the second "that" with "the".
Reword code comment "entries exist on on-disk index" in function
update_one in file cache-tree.c, by replacing incorrect preposition "on"
with "in".

The "--super-prefix" option to "git" was initially added in [1] for
use with "ls-files"[2], and shortly thereafter "submodule--helper"[3]
and "grep"[4]. It wasn't until [5] that "read-tree" made use of it.
At the time [5] made sense, but since then we've made "ls-files"
recurse in-process in [6], "grep" in [7], and finally
"submodule--helper" in the preceding commits.
Let's also remove it from "read-tree", which allows us to remove the
option to "git" itself.
We can do this because the only remaining user of it is the submodule
API, which will now invoke "read-tree" with its new "--super-prefix"
option. It will only do so when the "submodule_move_head()" function
is called.
That "submodule_move_head()" function was then only invoked by
"read-tree" itself, but now rather than setting an environment
variable to pass "--super-prefix" between cmd_read_tree() we:
- Set a new "super_prefix" in "struct unpack_trees_options". The
"super_prefixed()" function in "unpack-trees.c" added in [5] will now
use this, rather than get_super_prefix() looking up the environment
variable we set earlier in the same process.
- Add the same field to the "struct checkout", which is only needed to
ferry the "super_prefix" in the "struct unpack_trees_options" all the
way down to the "entry.c" callers of "submodule_move_head()".
Those calls which used the super prefix all originated in
"cmd_read_tree()". The only other caller is the "unlink_entry()"
caller in "builtin/checkout.c", which now passes a "NULL".

As with a preceding commit to convert "absorbgitdirs", we can convert
"submodule--helper status" to use its own "--super-prefix", instead of
relying on the global "--super-prefix" argument to "git".
We need to convert both of these away from the global "--super-prefix"
at the same time, because "update" will call "clone", but "clone"
itself didn't make use of the global "--super-prefix" for displaying
paths. It was only on the list of sub-commands that accepted it
because "update"'s use of it would set it in its environment.

The "--super-prefix" facility was introduced in [1] has always been a
transitory hack, which is why we've made it an error to supply it as
an option to "git" to commands that don't know about it.
That's been a good goal, as it has a global effect we haven't wanted
calls to get_super_prefix() from built-ins we didn't expect.
But it has meant that when we've had chains of different built-ins
using it all of the processes in that "chain" have needed to support
it, and worse processes that don't need it have needed to ask for
"SUPPORT_SUPER_PREFIX" because their parent process needs it.
That's how "fsmonitor--daemon" ended up with it, per [2] it's called
from (among other things) "submodule--helper absorbgitdirs", but as we
declared "submodule--helper" as "SUPPORT_SUPER_PREFIX" we needed to
declare "fsmonitor--daemon" as accepting it too, even though it
doesn't care about it.
But in the case of "absorbgitdirs" it only needed "--super-prefix" to
invoke itself recursively, and we'd never have another "in-between"
process in the chain. So we didn't need the bigger hammer of "git
--super-prefix", and the "setenv(GIT_SUPER_PREFIX_ENVIRONMENT, ...)"
that it entails.
Let's instead accept a hidden "--super-prefix" option to
"submodule--helper absorbgitdirs" itself.
Eventually (as with all other "--super-prefix" users) we'll want to
clean this code up so that this all happens in-process. I.e. needing
any variant of "--super-prefix" is itself a hack around our various
global state, and implicit reliance on "the_repository". This stepping
stone makes such an eventual change easier, as we'll need to deal with
less global state at that point.
The "fsmonitor--daemon" test adjusted here was added in [3]. To assert
that it didn't run into the "--super-prefix" message it was asserting
the output it didn't have. Let's instead assert the full output that
we *do* have, using the same pattern as a preceding change to
"t/t7412-submodule-absorbgitdirs.sh" used.
We could also remove the test entirely (as [4] did), but even though
the initial reason for having it is gone we're still getting some
marginal benefit from testing the "fsmonitor" and "submodule
absorbgitdirs" interaction, so let's keep it.
The change here to have either a NULL or non-"" string as a
"super_prefix" instead of the previous arrangement of "" or non-"" is
somewhat arbitrary. We could also decide to never have to check for
NULL.
As we'll be changing the rest of the "git --super-prefix" users to the
same pattern, leaving them all consistent makes sense. Why not pick ""
over NULL? Because that's how the "prefix" works[5], and having
"prefix" and "super_prefix" work the same way will be less
confusing. That "prefix" picked NULL instead of "" is itself
arbitrary, but as it's easy to make this small bit of our overall API
consistent, let's go with that.

Start passing the "super_prefix" along as a parameter to
get_submodule_displaypath() and absorb_git_dir_into_superproject(),
rather than get the value directly as a global.
This is in preparation for subsequent commits, where we'll gradually
phase out get_super_prefix() for an alternative way of getting the
"super_prefix".
Most of the users of this get a get_super_prefix() value, either
directly or by indirection. The exceptions are:
- builtin/rm.c: Doesn't declare SUPPORT_SUPER_PREFIX, so we'd have
died if this was provided, so it's safe to pass "NULL".
- deinit_submodule(): The "deinit_submodule()" function has never been
able to use the "git -super-prefix". It will call
"absorb_git_dir_into_superproject()", but it will only do so from the
top-level project.
If "absorbgitdirs" recurses will use the "path" passed to
"absorb_git_dir_into_superproject()" in "deinit_submodule()" as its
starting "--super-prefix". So we can safely remove the
get_super_prefix() call here, and pass NULL instead.

mboxrd is a more robust output format when used with --stdout
and needs more exposure. Introducing this config knob lets
users choose the more robust format for all their --stdout
uses.
Relying on --pretty=mboxrd and including all of pretty-formats.txt
in the `git format-patch' documentation would likely be
confusing to users. Furthermore, this setting is useful across
multiple invocations. So introduce `format.mboxrd' as a boolean
configuration knob that changes the default --pretty=email format

A previous change introduced the transport methods to acquire a bundle
list from the 'bundle-uri' protocol v2 command, when advertised _and_
when the client has chosen to enable the feature.
Teach Git to download and unbundle the data advertised by those bundles
during 'git clone'. This takes place between the ref advertisement and
the object data download, and stateful connections will linger while
the client downloads bundles. In the future, we should consider closing
the remote connection during this process.
Also, since the --bundle-uri option exists, we do not want to mix the
advertised bundles with the user-specified bundles.

Set up all the needed client parts of the 'bundle-uri' protocol v2
command, without actually doing anything with the bundle URIs.
If the server says it supports 'bundle-uri' teach Git to issue the
'bundle-uri' command after the 'ls-refs' during 'git clone'. The
returned key=value pairs are passed to the bundle list code which is
tested using a different ingest mechanism in t5750-bundle-uri-parse.sh.
At this point, Git does nothing with that bundle list. It will not
download any of the bundles. That will come in a later change after
these protocol bits are finalized.
The no-op client is initially used only by 'git clone' to test the basic
functionality, and eventually will bootstrap the initial download of Git
objects during a fresh clone. The bundle URI client will not be
integrated into other fetches until a mechanism is created to select a
subset of bundles for download.

Since aef7d75e580 (builtin/bundle.c: let parse-options parse
subcommands, 2022-08-19) we've been segfaulting if no argument was
provided.
The fix is easy, as all of the "git bundle" subcommands require a
non-option argument we can check that we have arguments left after
calling parse-options().
This makes use of code added in 73c3253d75e (bundle: framework for
options before bundle file, 2019-11-10), before this change that code
has always been unreachable. In 73c3253d75e we'd never reach it as we
already checked "argc < 2" in cmd_bundle() itself.
Then when aef7d75e580 (whose segfault we're fixing here) migrated this
code to the subcommand API it removed that "argc < 2" check, but we
were still checking the wrong "argc" in parse_options_cmd_bundle(), we
need to check the "newargc". The "argc" will always be >= 1, as it
will necessarily contain at least the subcommand name
itself (e.g. "create").
As an aside, this could be safely squashed into this, but let's not do
that for this minimal segfault fix, as it's an unrelated refactoring:

In order to make `--batch-check` option honour the mailmap mechanism we
have to read the contents of the commit/tag object.
There were two ways to do it:
1. Make two calls to `oid_object_info_extended()`. If `--use-mailmap`
option is given, the first call will get us the type of the object
and second call will only be made if the object type is either a
commit or tag to get the contents of the object.
2. Make one call to `oid_object_info_extended()` to get the type of the
object. Then, if the object type is either of commit or tag, make a
call to `repo_read_object_file()` to read the contents of the object.
I benchmarked the following command with both the above approaches and
compared against the current implementation where `--use-mailmap`
option is ignored:
`git cat-file --use-mailmap --batch-all-objects --batch-check --buffer
--unordered`
The results can be summarized as follows:
Time (mean ± σ)
default 827.7 ms ± 104.8 ms
first approach 6.197 s ± 0.093 s
second approach 1.975 s ± 0.217 s
Since, the second approach is faster than the first one, I implemented
it in this patch.
The command git cat-file can now use the mailmap mechanism to replace
idents with canonical versions for commit and tag objects. There are
several options like `--batch`, `--batch-check` and `--batch-command`
that can be combined with `--use-mailmap`. But the documentation for
`--batch`, `--batch-check` and `--batch-command` doesn't say so. This
patch fixes that documentation.

Even though the cat-file command with `-s` option does not complain when
`--use-mailmap` option is given, the latter option is ignored. Compute
the size of the object after replacing the idents and report it instead.
In order to make `-s` option honour the mailmap mechanism we have to
read the contents of the commit/tag object. Make use of the call to
`oid_object_info_extended()` to get the contents of the object and store
in `buf`. `buf` is later freed in the function.

diff: remove parseopts member from struct diff_options
diff: use add_diff_options() in diff_opt_parse()
diff: factor out add_diff_options()

The editor program used by Git when editing the sequencer "todo" file
is determined by examining a few environment variables and also
affected by configuration variables. Introduce "git var
GIT_SEQUENCE_EDITOR" to give users access to the final result of the
logic without having to know the exact details.
This is very similar in spirit to 44fcb497 (Teach git var about
GIT_EDITOR, 2009-11-11) that introduced "git var GIT_EDITOR".

"git var UNKNOWN_VARIABLE" and "git var VARIABLE" with the variable
given an empty value used to behave identically. Now the latter
just gives an empty output, while the former still gives an error
message.
