None of the above, including the existing "origin/*" lets people cut
and paste the left-hand-side (which is what is available locally to
them) to a command line, e.g. after seeing

     From github.com:git/git
        a7da99ff1b..28d0017056  next                -> origin/*

you cannot append "origin/next" after "git log .." with a few
mouse-clicks.  As the actual object name after the update appear
with the double-dot, "git log ..28d0017056" is also hard to create
without dragging a7da99ff1b part from the output.

Having said that, I do not do pointy-and-clicky cut&paste myself, so
it would not bother me that much and any of these "compaction" ideas
may be OK.  Using the refmap notation would start bothering people
for perceived repetition of that right-hand-side, though.
