[PATCH] Add test that checks diverse aspects of updating remote and tracking branches

[Alex Riesen <raa.lkml@gmail.com>]

Because we haven't settled on what the exit status from
"git push" command itself should be in such a partial
failure case, do not check the exit status from it for
now.

Add test that checks diverse aspects of updating remote and tracking
branches.

This I'll leave as is.

Yep.

Nice, will take this. Except we have to check for absence of the
tracking branch. git-rev-parse must fail.
