Oh, no, I don't intend to give the impression that VM is mixed up in any 
way.  Almost all the code written before the present compiler warning 
was using the save-excursion/set-buffer combination.  It is in inherent 
in that combination that it covers up bugs involving unprotected point 
movements.

The only thing special about VM is that it deals with multiple buffers 
and switches between them a lot.  So, it is incredibly hard to track 
down the unprotected point movements.  For all I know, there could be a 
couple of problems.  But it will be a lot of hard work to find them.
