It fells that this is presented backwards.  The usefulness of the
layout that names local branches deliberately differently from their
remote counterparts needs to be justified first.  Only after that,
we can consider adding extra mechanism to support such a layout.


Once "git checkout foo" is taught to do the same as "git checkout -b
extra-foo -t origin/foo", it would create

	[branch "extra-foo"] 
		remote = origin
		merge = refs/heads/foo

but the push side would need extra work, and that is why you needed
to muck with the push refspec.  But then what should happen when the
user is using "we do not bother remembering what branches to push
there; the remote repository remembers that for us", aka "matching
push"?

Most of the problems is what you are creating by using an unusual
layout to name local branches differently from the remote
counterpart.  You do not have to, and then all the problems you
created with that layout goes away, without this patch.

So, I am not sure if this is a good idea to begin with.  At least, I
am not yet convinced.

Thanks.
