The proposed fix-up is for a part of git.c that only exists with your
series applied.

Before your series "git bisect--helper" supported
"--git-completion-helper" (although not to do anything useful in
practice).

With your series we have a "bisect" built-in. Built-ins by default claim
to support "--git-completion-helper", but as your series also migrated
the code away from parse_options() it doesn't anymore.

So it makes sense for the relevant patch(es) to update the corresponding
flag as that's changed, see also the in-flight 68494127d6c (git.c:
update NO_PARSEOPT markings, 2022-07-25).
