COL vs CLMAN

[rconn at brl]

From:      Rick Conn <rconn at brl>

I received a message from someone on this list saying that col is
the same as clman.  According to my man entry on it, it is not.  col
filters reverse line feeds.  clman filters man-generated sequences
for boldface and underline, i.e., it deletes the "<underline><backspace>"
and "<backspace><character>" (in that order) sequences from stdin
and forwards all else thru stdout.

As a side note, I used man on a DUAL 68000 UNIX Version 7 today and
it did not have the problem.  It appearantly looked at the device it
was sending output to, saw it as a CRT, and didn't send those sequences
out.  I still run into the problem on BRL's man and UNIX III, and that's
what clman is good for.
