[PATCH v6 0/4] push: submodule support

Hi,

this is the sixth iteration of this series which should contain all discussed cleanups from the last iteration. The testsuite was hanging for me with make -j5 on Mac OS X 10.6.8. I doubt that it was because of any change in series but please verify as well. A non parallel run passed. If I find some time I will try to bisect that.

Cheers Heiko
