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.
The reason is commit 73136b2e8a
by Dscho: it
adds calls to git-repo-config in git-parse-remote.sh to get the remote
shorthands etc.
Now, either we should just hide and ignore the error from git-repo-config
(probably bad, because some errors _are_ valid - like git-repo-config
failing due to bad syntax in the config file), or we should just make
git-repo-config quietly handle the case of not being in a git repository.
This does the latter: just quietly accepting (and doing nothing - trying
to set a value will result in the lock-file failing) our lot in life
sounds better than dying with a bogus error message.
