I'll have to admit I know ditroff source a lot better than old troff
source.  As a matter of fact, I can't even understand old troff code.
Does anybody know how to modify old troff (probably t10.c) so it can
produce lines longer than 7.54 inches?  Using TranScript like this:

	% ptroff -L
	.pl 8.5i
	.ll 9i

pages come out in landscape mode (lines going across the long side of
the paper), but troff crunches lines into a 7.54 inch wide area, which
makes them very hard to read.  I'm sure old troff does this because the
CAT/4 had very narrow paper rolls.  I ask this question not for myself
(I use ditroff) but for Sun customers too poor to pay for ditroff.

Thanks in advance,
