[PATCHv3 0/7] submodule update: allow '.' for branch value

This got bigger than expected, but I am happier with the results.

The meat is found in the last patch. (At least what I am interested in; others may be more interested in the second patch which could be argued to be a real bug fix to be merged down to maint.)

Thanks Junio for the thourough review of the first patches, Stefan
