In GNU Emacs 18.55.8 of Tue Jul 31 1990 on ittc (berkeley-unix)

Here is a patch for man.el

It makes the following modifications.

1) The output buffer is named *topic man*.  This was originally sent out on
the net before and I snarfed it up then. Sorry I lost the posters name.  

2) Pops to the appropriate *topic man* buffer if it exists instead of
having to reformat and re-clean the page again.

3) Nukes a little more BS that is created by the Sun man pages.

4) Makes sure the man page is readonly to prevent accidental editing, and
kludges the keymap to do scrolling ala view-mode.


enjoy
