Exactly.  IMO, if the variable can have a
nonfunction value, especially nil, then
there's no need (nothing gained, and even
possible confusion/misunderstanding added)
by adding "-default-" to the name.

On the other hand, if the value must always
be a function, then having "-default-" in
the name makes sense.

Following this guideline helps users know
(guess) what the variable's value can be
even without consulting its doc.
