Hi.

Commit 460d5fd971489ba7b573d71a94cdaac2f9f1a767 introduced a new
function `count-sentences', which is nice, but it also silently changed
the return value of `forward-sentence' (and thus also
`backward-sentence') from returning the new value of point to returning
t/nil based on whether point moved or not.

I just discovered this because it caused one of my packages to break,
since it relies on the previous style return values from
`forward-sentence'/`backward-sentence'. It would be easy enough fix on
my part, but I'm wondering whether this change was intended, and if so,
whether it should be documented somewhere so package authors can adapt
more easily?

Or could perhaps the change in return values from
`forward-sentence'/`backward-sentence' be reverted to old behavior, and
the counting logic be left to `count-sentences' instead?
