We definitely need to keep the -1 offset there.  (It was previously
supplied by ispell-offset, but that variable was deleted.)  The reason
for the offset is that the line we send to the speller has a "^"
prepended to it (see the documentation of the Ispell interface for the
reason why).

Please add a comment to that effect when you commit the above.

Thanks.
