I'm getting a reproducible "too many nested undo groups" message

But I don't know what to look for because I don't know what that
means. How many is "too many"? Of what? Is there any way to see
the number?
Here is what I have found by experiment:
Whenever I -beginUndoGrouping, -groupingLevels is incremented.
Whenever I -endUndoGrouping, -groupingLevels is decremented.
If I -endUndoGrouping when -groupingLevels is 0, I get an
exception: -endUndoGrouping invoked with no matching begin.
All this makes sense. Then, by extension, "too many nested undo
groups" implies that -groupingLevels is too high. But by default, -
levelsOfUndo is inifinite.
Levels of undo and nested undo groups are separate things, I think.
The message is most likely being generated because you're missing an -
endUndoGrouping message somewhere.
Kind regards,
Alastair.
