Description of Problem:

M-x man dispays control codes in addition to face changes when displaying manual
pages.

Version-Release number of selected component (if applicable):

emacs (21.2.90, still....)

How Reproducible:

always

Steps to Reproduce:
1. M-x man RET ls RET

Actual Results:

You see something like this:

LS(1)                            User Commands                           LS(1)

NAME
       ls - list directory contents

SYNOPSIS
       ls ^[[22m[^[[4mOPTION^[[24m]... [^[[4mFILE^[[24m]...


Expected Results:

You should see something closer to this:

LS(1)                          FSF                          LS(1)

NAME
       ls - list directory contents

SYNOPSIS
       ls [OPTION]... [FILE]...



Additional Information:
	
I'm a bit confused as to what's causing this.  Perhaps a change in groff output?
 I have not investigated it or reported it to bug-gnu-emacs (or the pretest
list) because it appears to be a RedHat issue.

This does not happen on RedHat 7.3.  I don't think it happened on Limbo either
because I'm sure I would have noticed it as I use M-x man often.  (Both my Limbo
systems are now running (null), so I can't check.)

This happens even with

LANG=C emacs -q --no-site-file

so, at first glance, it does not appear to be locale-related.  This does not
happen with emacs 21.2.90 compiled on (null) and run on RedHat 7.3 (with
/usr/lib nfs-mounted from a (null) system in its LD_LIBRARY_PATH).

Please let me know if you need me to further investigate.
