Attached is a finished version that includes hooks for all the variables
for which they were clearly sensible. (FETCH_COUNT doesn't seem to really
need one, and I didn't do anything with HISTSIZE or IGNOREEOF either.
It might be worth bringing the latter two into the hooks paradigm, but
that seems like fit material for a separate patch.)
I updated the documentation as well. I think this is committable if
there are not objections.
