Message-ID: <20161227175013.12747-1-sbeller@google.com> (raw)
In-Reply-To: <7E1C7387-4F37-423F-803D-3B5690B49D40@gmail.com>

When the worktrees directory is empty, the `ret` will be returned
uninitialized. Fix it by initializing the value.

This goes on top of 1a248cf (origin/sb/submodule-embed-gitdir);
ideally to be squashed, but as it is in next already, as a separate
patch.

Thanks,
Stefan
