Yes.

That takes care of letting users set the default behavior,
yes.

It doesn't, however, tell them anything about being able
to hit a key while searching to toggle the current behavior.

If you add defcustoms and then mention in their doc strings
that the _current_ behavior can be toggled with `M-s SPC'
then that would take care of this bug report.

Users will naturally want to (1) set their preferred default
behavior or (2) toggle the current behavior, or both.  The
point is to help them better to know how they can do these
things (which they can do already).
