[RFC] make --set-upstream work for local branches not in refs/heads

[Krzesimir Nowak <krzesimir@endocode.com>]

It might be possible (in "Gerrited" setups) to have local branches
outside refs/heads/, like for example in following fetch config:

[remote "origin"]
	url = ssh://user@example.com/my-project
	fetch = +refs/heads/*:refs/remotes/origin/*
	fetch = +refs/wip/*:refs/remotes/origin-wip/*

Let's say that 'test' branch already exist in origin/refs/wip/. If I
call:

git checkout test

then it will create a new branch and add an entry to .git/config:

[branch "test"]
	remote = origin
	merge = refs/wip/test

But if I create a branch 'test2' and call:

git push --set-upstream origin test2:refs/wip/test2

then branch is pushed, but no entry in .git config is created. I have
to do it manually. I attached a hack-patch to have it working just to
check with you if anything like that would be accepted. Obviously the
get_local_refs() would need to compute the actual list of local
hierarchies (if it is possible at all). And it probably should get a
better name. And probably something else.

What do you think?
