Newpage appearance

[Matthias]

Hi,

In Text mode (with Enriched mode turned on), and under X, I remember
that one day the newpage character (i.e. ^L) was replaced by a line of
dash like  the following:

---------------------------------------------------------------------

I am not able to get this behavior back (same file, emacs & computer)!
Anybody knows how to turn this feature on? Is a non-official library
neede for this?

Thanks for your help.
