I shared the above understanding with you, so I didn't find the name
"not very descriptive" during my review.  If only we had two more
functions that can replace our uses of repo_git_path(r, "config")
and repo_git_path(r, "config.worktree") [*] in the code, to obtain
the path to the repository local and worktree local configuration
files, the convention may have been more obvious.

    Side note: the worktree specific one is messier; there are code
    paths that use "%s/config.worktree" on gitdir as well---if we
    were to introduce helpers, we should catch and convert them, too.

I do not mind including "path" in the names of these functions, but
I do agree that such renaming should be done consistently across the
family of functions (which we currently have only two members, but
still).

Thanks.
