[RFC] add test cases for the --repo option to git push

[Michael J Gruber <git@drmicha.warpmail.net>]

The --repo=myorigin option is supposed to change the default fallback
remote from "origin" to "myorigin", but not override any direct argument
nor config info of tracking branches. Add tests for this. (currently 2
known breakages)

Tap tap tap....

This is an R for Comments on the desired behaviour of git push with
respect to --repo. I think the tests below expose that the current
behaviour does not match the current doc. I'm messing around in the code
but can't quite produce a match with the doc yet. Before investing more
time I'm wondering whether the code should adjusted to the doc or vice
versa...

The code change I'm experimenting with right now is making
default_remote_name a global and passing it from push. Does not look
nice (esp. w.r.t. libification) but seems to ibe the minimally invasive
solution.
