Remove a check for inclusivity in select_to_reverse.

It turns out that neither <a-f> or <a-t> make sense when run at the
beginning of the buffer. When I first created the check, I thought
that <a-f> made sense if the character under the cursor was the
character being searched for.  I was wrong, <a-f> should always go
at least one character backwards.
