Merge branch 'jn/remote-helpers-with-git-dir'

Browse Source 
"git ls-remote" and "git archive --remote" are designed to work
without being in a directory under Git's control.  However, recent
updates revealed that we randomly look into a directory called
.git/ without actually doing necessary set-up when working in a
repository.  Stop doing so.

* jn/remote-helpers-with-git-dir:
  remote helpers: avoid blind fall-back to ".git" when setting GIT_DIR
  remote: avoid reading $GIT_DIR config in non-repo
