Thanks for that, it mostly works, however it doesn't seem to notice if I
abort without making the merge complete (on emacs21).  In my smartmerge
script (http://utsl.gen.nz/scripts/smartmerge) I detect this condition
based on the presence of merge markers, possibly dubious but pragmatic.

I still don't really understand why having to save the merged buffer and
exit is such a huge issue.  Already I have to select "-t emerge" to get
emerge.  I would have thought it would be better to just make the other
mode available, and let the user figure it out.
