OK, time for the drive-by patch commenting.  I've largely stayed
out of git-submodule related code, but I just looked at in the
context of applying this patch.

There are three callers to resolve_relative_url in master and next.
All three callers just "|| exit" when resolve_relative_url fails.

The only reason resolve_relative_url can fail is when there is no
remote.$remote.url configuration option set for the current default
remote ("origin"?).

I guess I'm unclear about why cmd_sync is different from the
existing callers.
