Subject: Re: Bug: All git operations fail when .git contains a non-existent gitdir

The easiest way to reproduce it is this:

$ mkdir test
$ cd test
$ echo "gitdir: /foo/bar" > .git
$ git ls-remote

We happen to use overlay mounts in our build system in a way that maps
a git submodule from one place to another so that its "gitdir" is
invalid and then attempt a `git ls-remote` from that location which
unexpectedly fails.  But the above reproduces the problem well enough.
