[PATCH v2 0/3] Speedup finding of unpushed submodules

[Heiko Voigt <hvoigt@hvoigt.net>]

You can find the first iteration of this series as part of this thread:

http://public-inbox.org/git/%3C20160914173124.GA7613@sandbox%3E/

All mentioned issues should be fixed. I dropped the last patch which was
the cause of the broken tests.

This should optimize every part of this test to a nice speed if you are
pushing to a remote. The only case that is still broken/slow as hell is
when calling push with a direct url.

I am thinking whether we should maybe error out with a "not implemented"
message or something and mention that --recurse-submoules does not work
with direct urls? But we might want to have another look at performance
with this patch included. Maybe it is actually useable with the last
patch included which was not yet on pu.

Cheers Heiko
