OK, I've found and checked in the correct fix for the bug.  I also
reverted my original, deeply flawed fix.

FWIW, the original bug was caused by a 2006-09-17 change to dispnew.c
to avoid redrawing a whole row if it has mouse-face in it.  The
rationale for this change was that this was causing excessive
flickering of mode lines.  So I've made it so that we redraw a row if
it has mouse-face in it, except if it's a mode line.

Thanks for the feedback, and sorry for the false start in fixing this
