Good.  The caller always calls this function with the_repository, so
this patch does not change anything in the bigger picture.

Isn't it still relevant to explain the reason why this codepath
avoids calling the repo_get_git_dir() function?

e5b17bda (git: ensure correct git directory setup with -h,
2021-12-06) tells us that the comment is about use of
startup_info->have_repository, which was added by a9ca8a85
(builtins: print setup info if repo is found, 2010-11-26).
