Menu: Help -> Manuals -> Read Man Page... problem

Subject: Menu: Help -> Manuals -> Read Man Page... problem

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.3.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2004-02-24 on pcl321
configured using `configure  ix86-linux-gnulibc2 --prefix=/usr/local'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: nil
  locale-coding-system: nil
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

If I use the emacs menu: Help -> Manuals -> Read Man Page...
to view a unix manpage I get bad output. The reason is, that since
groff-1.18.1 the output from 'groff -Tlatin1 -mandoc' contains SRG
escape sequences (ISO 6429, or ANSI color escapes) that emacs doesn't
display properly.

The same problem occured with xman from XFree86-4.3.0 (and maybe earlier).
There the solution was to invoke groff with a suitable environment variable:
      GROFF_NO_SGR= groff -Tlatin1 -mandoc

The alternative to invoke groff with '-c' is not viable because (1) that flag
is not understood by groff-1.17.x and (2) even for groff-1.18.1 seems not to
work as advertised.
