In GNU Emacs 21.3.1 (i386-msvc-nt5.1.2600)
 of 2003-03-27 on buffy
configured using 'configure --with-msvc (12.00)'
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: ENU
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

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

Running emacs 21.3.1 on W32 with MKS toolkit, I found that there were
some ANSI sequences not handled by Man-fontify-manpage. I was able to
work around with Man-cooked-hook, but I though others would appreciate
having this done by default in Man-fontify-manpage. 

I've appended our local workaround. I tried to contact the man.el Author:
Barry A. Warsaw <address@hidden> but the email bounced.
