I don't know.  But it shouldn't be excessively hard --- even Java's AWT 
can do it ;-)

In the existing framework, that's one of only two possibly sane ways of 
doing it (the other: keep only the last page).

It might, if someone manages to pull it off and find an understandable
user interface.  I would imagine something like

	set output 'filename' numbered

(maybe with some options to control how the numbers are put into the name).

The main benefit of this approach would be that it would work for other 
file-based terminal drivers, too.
