No, you told just part of it:

Can you please make this more explicit?  Please show what I need to
type in Emacs to accomplish what you say here.

If you tell me how to define the fill prefix, I can test myself.

What I implemented came out of the sub-thread of this thread where I
explained to Stefan why I think it sometimes recenters, and Stefan
agreed that fixing that is a good idea.  See

    http://lists.gnu.org/archive/html/emacs-devel/2010-06/msg00773.html

for details.  In a nutshell, the problem I fixed was that Emacs didn't
look for point far enough beyond the end of the window.
