* lisp/savehist.el (savehist-autosave-interval):
Correctly reset 'savehist-timer' when savehist-autosave-interval changes
via setopt or a Customize command.

An open question is should the timer be an idle timer or not. Currently,
the timer is a regular timer. I'd prefer an idle timer. Not sure how many
people would care if this changed.
