Please realise what I've been trying to tell you: there is a difference in
the user experience when one types `man ppp` on a 4.8 box and when one
types `man ppp` on a 5.1-B box. On a 4.8 box the user types `man ppp`,
gets a message, then waits around 10 seconds for the page to display. On a
5.1-B box the user types `man ppp` and DOES NOT GET A MESSAGE BUT HAS TO
WAIT 10 SECONDS before the page is displayed.
You keep saying that the page will be displayed quickly because groff is
piping it to the pager, but this does not happen - there is always a
considerable delay perhaps because groff is formatting..

I want the same behaviour as is in 4.8-RELEASE.

So it IS a root vs. non-root thing, because non-root cannot create a
catpage anymore.

Scene 1 does not happen for a Normal user anymore. Please understand this.
The message does not appear to the user.
