I think it's highly sub-optimal to have a local-branch @{u} for
several reasons; the prompt is almost useless in this case, and it
will always show your forked-branch ahead of 'master' (assuming that
'master' doesn't update itself in the duration of your development).
While doing respins, the prompt doesn't aid you in any way. Besides,
on several occasions, I found myself working on the same forked-branch
from two different machines; then the publish-point isn't necessarily
always a publish-point: it's just another "upstream" for the branch.
The point of a special branch.*.forkedFrom is that you can always show
the "master..@" information in the prompt ignoring divergences; after
all, a divergence simply means that you need to rebase onto the latest
'master' ('master' is never going to get a non-ff update anyway).

So, instead of crippling the functionality around the publish-point,
let's build minimal required functionality around branch.*.forkedFrom.
I'd love a prompt like:


Clearly, branch-forkedfrom has diverged from my publish-point (I'm
probably doing a respin), and has 5 commits (it's 5 commits ahead of
'master' ignoring divergences).

I think a @{publish} is needed for when branch.*.remote is different
from remote.pushDefault. Like I said earlier, it's probably too much
information to give to the user: divergences with respect to two
remotes. So, we'll hold it off until someone finds a usecase for it.
