repo-config needs a prefix.

This fixes the message received when invoking certain commands from outside of a git tree, so e.g. instead of receiving this:
/home/rob/bin/git-fetch: line 89: /FETCH_HEAD: Permission denied
We get this again:
fatal: Not a git repository: '.git'

While I do agree that it would be better to give nicer message when running "git-fetch" in bogus places, I do not know if your patch is the right fix. Especially, I am not sure if this change meshes well with this fix a few months ago.

bogus "fatal: Not a git repository"

I was just testing that "git ls-remote" change by Junio, and when you're not in a git repository, it gives this totally bogus warning. The _target_ obviously has to be a git repository, but there's no reason why you'd have to be in a local git repo when doing an ls-remote.

Hi,
