parse-options: detect ambiguous self-negation
Git currently does not detect the ambiguity of an option that starts
with "no" like --notes and its negated form if given just --n or --no.
All Git commands with such options have other negatable options, and
we detect the ambiguity with them, so that's currently only a potential
problem for scripts that use git rev-parse --parseopt.
Let's fix it nevertheless, as there's no need for that confusion. To
detect the ambiguity we have to loosen the check in register_abbrev(),
as an option is considered an alias of itself. Add non-matching
negation flags as a criterion to recognize an option being ambiguous
with its negated form.
And we need to keep going after finding a non-negated option as an
abbreviated candidate and perform the negation checks in the same
loop.
