Hi. Why not a "dirty" flag? There might be one already there; I don't
remember if Dia asks me to save the file before closing if it was
changed since opened.

It's there, in fact it's a bit more complex than just a flag by now:  We
can actually notice that changes have been undone and mark it
non-modified.  The check is diagram_modified(Diagram), AFAIR.  The
'virtual' flag is to indicate that this is a starting diagram that can
be loaded into.  Wouldn't want a user to explicitly make a new diagram
and then open another, only to find that the opened diagram 'ate' the
new diagram.

Another way to look at that, fwiw, is 

        Virtual == !dirty && empty

That would mean that a diagram that had its contents deleted and saved
(hope that's clear) would recover its original virtualness.
