sequencer: truncate labels to accommodate loose refs
Some commits may have unusually long subject lines. When those subject
lines are used as labels in the `--rebase-merges` mode of `git rebase`,
they can cause errors when writing the corresponding loose refs because
most file systems have a maximal file name length of 255 (`NAME_MAX`).
The symptom looks like this:
$ git rebase --continue
error: cannot lock ref 'refs/rewritten/SANITIZED-SUBJECT': Unable to create '.git/refs/rewritten/SANITIZED-SUBJECT.lock': File name too long - where SANITIZED-SUBJECT is very long
Let's accommodate this situation by truncating the labels.
Care must be taken in case the subject line contains multi-byte
characters so as not to truncate in the middle of a character.
