Looks good to me.  Ola, can you check whether Robert's patch fixes
horizontal scroll bars on your system?

Could you refactor them?  Note that unless you have done so already, you
will probably have to sign papers anyway so that we can install your
patch.  If you don't sign, we can probably apply the fix for vertical
scroll bars at most.  Eli will decide how to proceed then.

How?  Is the mode line of the window above fully visible or does the
horizontal scroll bar overdraw the mode line of its window and the echo
area?

Thanks for your continuous efforts to get this working, martin
