If people are getting confused about where the message begins and
ends then that's an interrface problem.  This is something that
should be addressed in VM itself rather than in a hook function.
I tried to address the problem once by using the Emacs overlay
arrow feature but it would either make GNUS crash, or disappear
when the user changed windows, or display the arrow string on
every screen line after the end of buffer position.  Maybe I
should just put "More..." in the echo area... ?

I think I will make the whole message be within the clipping
region in all cases.
