Re: [PATCH v2 09/11] git-gui: allow specifying path '.' to the browser

> Invoking "git-gui browser rev ." should show the file browser for the
> commitish rev, starting at the current directory. When the current
> directory is the working tree root, this errors out in normalize_relpath
> because the '.' is removed, yielding an empty list as argument to [file
> join ...]. The browser function demands "./" in this case, so make it
> so. (./ works on Windows as well because g4w accepts posix file
> naming).
