I've noticed that M-up and M-down no longer move by paragraphs, but by
sentences instead. OTOH, C-M-up and C-M-down now move by paragraphs.
Ben, is that your change? What's the motive behind it? I don't claim
that the new behaviour is either better or worse than the old one, but
I'm definitely used to the old bindings, so the change comes as a bit
unnerving to my XEmacs-trained fingers.
