I had to reread it just now, to remind myself what
this is all about. ;-)

Thanks, Mauro.  I don't have the time now to
check the result, but I have no problem at all
with whatever fix you implemented.  If later
(probably much later) I find something I think
could be improved more in this regard, I'll
file a new enhancement/bug request.

Thx!
