That description of the problem you are trying to solve makes (sort
of) sense.

Hmmph.

I do not know if this will help any case you described above, even
though this might help some other cases.  The added output is to
always show the current branch and its upstream, but the thing is,
the original issue in $gmane/198703 was *not* that the current
branch was pushed and up to date.  It was that there was no current
branch to be pushed.  The same thing would happen if you are on a
local branch that is not set to be pushed to the other side
(e.g. the configuration is set to "matching" and there is no such
branch on the other end).

"Your branch is identical to" will be given only if your branch is
set to be pushed out, no?  For the user to tell what is going on,
the user has to notice the lack of this extra line in the output,
and noticing the lack of anything is much unlikely.
