[PATCH v1 01/11] git-gui: allow specifying path '.' to the browser

[Mark Levedahl <mlevedahl@gmail.com>]

Invoking "git-gui browser rev ." should show the file browser for the
commitish rev, starting at the root directory. This errors out in
normalize_relpath because the '.' is removed, yielding an empty list as
argument to [file join ...]. Fix this.
