A new HasAutoFormat (only) called from ~ScAutoFormatObj would of course 
solve the immediate problem, too.

However, whether it actually would be an advantage to not have to 
address the other calls to GetAutoFormat, I am not sure.  After all, 
those calls that afterwards check for null-ness *are* dubious.
