and it almost works as expected.  The third-to-last and second-to-last

of the next page.  The last line is never printed! 

I'm amazed it worked that well, seeing as I'm no expert on diversions
and I didn't even try the code. :-)

It sounds like the diversion's not getting completely flushed out. Try
adding a ".br" request at the beginning of ParEnd:

.de ParEnd\"                        End paragraph diversion.
.  br\"                              Flush out the last line.   If all but
.  di\"                               two lines of the paragraph will
.  if (\\n[.t] < (\\n[dn]-2v))\#      not fit on this page, set a trap
.    dt \\n[.h]u+\\n[dn]u-2v ParBP\"  for two lines from the bottom of
.\"                                   the paragraph.
.  ParDIV\"                         Print the paragraph.
..

If that doesn't work, I must defer to someone who knows diversions
better. Here's a pointer to Thomas Baruchel's attempts as well, maybe
you'll find some inspiration:

I probably should try studying the widow&orphan code & see if I
can get it to work... just one more thing I don't have the time for. :-)
