[PATCH] git-submodule - Fix errors regarding resolve_relative_url

[Mark Levedahl <mlevedahl@gmail.com>]

git-submodule was invoking "die" from within resolve-relative-url, but
the error return was ignored by the callers. Fix this.

While we're at it, clean up the quoting on invocation of
resolve_relative_url as it was wrong.
