Sorry, I should have removed my draft commentary before submitting.
Yes, you are of course right.

Interesting idea. However, moving it into parse_options() presumes
that either `git_default_config` will always be passed to
git_config(), or else the arguments needed by git_config() will be
explicitly passed to parse_options. A quick grep through the source
code suggests that only about 1/3 of callsites pass git_default_config
to git_config(), and passing a config-related callback function to
parse_options seems a little weird to me. Plus, the fact that 2/3 of
the callsites use a special config callback function suggests that
we'd still not catch all cases with such a change, much like I had to
update the upload_pack_config special callback below.
