a few Topgit patches

Hello,

I hacked using topgit for some time now, and found the following changes to topgit useful:

Uwe Kleine-König (3):
      tg export: implement skipping empty patches for collapse driver
      tg export: Implement flattening patch paths for quilt mode
      tg export (quilt): Implement numbering the patches

You can fetch or pull these from

	git://git.pengutronix.de/git/ukl/topgit.git master

or browse them using the following URL:

For review I send the patches as a reply to this mail.

Best regards Uwe
