The idea makes sense, but I am not sure the implementation is
correct. Does the code already know the final value of use_editor
at the point where it calls git_commit_config? I think you do not
know at least until you call parse_and_validate_options().
Once you got the implementation right, we would want to make sure
that future changes will not break it by adding some tests that
verify:
- Without configuration and without option, the command keeps the
built-in default;
- Without configuration but with option, the command uses the
command line option (we may already have this test, I didn't
check);
- With configuration and without option, the command uses the
configured default (what this patch adds); and
- With configuration and with option, the command uses the command
line option.
The latter two probably needs a few variants, one with --edit (with
EDITOR set to something like "true"), another with --no-edit, one
without --edit nor --no-edit but with -m "$msg" to implicitly turn
use_editor off, and one without --edit, --no-edit, nor -m but with
EDITOR set to a scriptlet that writes a message to the file to
implicitly turn use_editor on.
Also, the readers of the documentation for "commit --cleanup" will
wonder the same thing you wondered before you wrote this patch;
mentioning the configuration variable in its documentation will help
them.
Thanks.
