[Groff] plain ascii w/o control chars

[Ricardo Fabbri]

Hi, folks!

A naive question for y'all:

I have some manpages containing numerous .B, \fB and \fI
directives.  How do I generate plain ASCII output, WITHOUT ANY
CONTROL CHARACTERS OR ESCAPE SEQUENCES??

I could remove the typeface formatting,
but that would generate poor .html or .ps output.

I tried to use "colcrt" filter, but it removes underscores,
which I wish to keep untouched.

Thanks in advance,
and sorry if I'm doing any stupid mistake....
Ricardo.
