Hi Michael,

I am scratching my head - how could one re-implement

+  if (A && !B)
-  if (A && B)

or any other trivial fix? I believe the following logic-manipulating 
approach is pure dotage:

+  if (A && !B)
-  if (A && !(!B))

+  if (A && !B)
-  if (!(!A || !B))

isn't it? :) Or one need to rewrite UndoManager...

I don't know if the patch can be considered a key-fix, the bug title is:

"Undo broken in several contexts (Basic Editor, Math Editor, Calc Input 
Line, MultiLine controls, etc)"

(you know, it depends on the definition of the key-fix... :) From my 
point of view it can, but I am an inveterate bug-hater.

Regards,
