Thanks, please accompany this with a suitable change in NEWS which
announces this new feature.

This single line doesn't tell in enough detail when the hook is run.
"Before setting spellchecker parameters" does not necessarily explain
itself clearly enough, because the reader doesn't necessarily know
where these parameters are set in the sequence of actions performed
for spell-checking.  Please add more explanations about that.  In
particular, I think it's important to understand whether this is
called before each invocation of the spellchecker, or just some of
them.
