Ah, yes.  My finger slipped.  I meant to type ScDB*, not ScDP*. :-P  So
many ScFooCollection in Calc core...  Glad you caught that. :-)

Normally we would want undo to work unless there is a good reason to
skip it.  For things that are invisible to the user (like the anonymous
DB ranges), however, let's make it undoable if it affects the behavior
of autofilter.  If not, then let's not worry about that.

My only concern is that, when the document is saved, all the anonymous
ranges need to be saved with the document.  When you undo the anonymous
DB creation then immediately save the document, we may save unnecessary
anonymous ranges to the document.  This may not be a big deal in
practice, but is something to be aware of.

Good to hear that.  I wasn't sure 100%...
