It was a rather old bug (ultimately, one of my changes).  I made a fix for
that (part of ongoing 9.8n updates - attached).  While we're in this area,
I have an (old :-) to-do item to provide a way for macros to group undo's
into larger chunks, so that a macro could be undoable.

Most of my other to-do items deal with new/improved syntax filters,
but I think that focusing on the undo functionality might be a better
goal for 9.8n.
