I had a similar thought. But note that we do update "branch.*.remote"
that points to the renamed remote. So it seems inconsistent that we do
not similarly update "branch.*.pushremote". And if we update that, it
seems inconsistent that we do not update "remote.pushdefault".

In other words, we should probably choose to update all references or
none, but we are currently somewhere in between. Of course, the fact
that the code has been in this limbo for so long makes it doubly
awkward, as we do not know what people expect (and what they simply
consider a bug).

So I don't know what the right answer is.

I did take a peek at the code. I don't think updating these variables
would be too hard, but there needs to be some refactoring around
remote.c's pushremote_name.  After calling read_config(), we do not have
a value that exactly corresponds to remote.pushdefault; we overwrite it
with the branch-specific pushremote if there is one.
