I can see why you'd be surprised if you think of "-C" as "change to this
git repo". But it really is "change to this directory". It is perfectly
OK to "git -C" into a non-toplevel directory of a repo (and continue
respecting any repo discovery that happened already and is in the
environment), or even weird stuff like:

  GIT_DIR=/some/repo.git git -C /some/worktree add foo

What you almost kind-of want is "--git-dir", except it puts the onus on
the caller to find the actual repo directory (so detecting bare vs
discovering the .git). Part of the point of introducing -C long ago was
because --git-dir was so annoying to use.

Probably there is room for some middle-ground option, which is "do repo
detection starting in this directory and use that as the --git-dir" (and
I guess also do worktree discovery in the same way). But I don't think
we would ever switch -C to that. It would almost certainly break lots of
people if we changed it now.
