pushmod: do not delete the whole branch when deleting .hgsub When deleting .hgsub, and only .hgsub, the root directory '' was marked as changed. Since it was not listed in the existing directory list, this single record was enough to trigger a deletion of the current branch. We changed the directory parser to always emit the '' element.
