This sentence isn't true because the value can be any function,
including one that does nothing.

I think this would be much better if the options were: the symbol
`replacement-only', the symbol `both', or a custom function.  Most users
will not need to write a custom function and these shorter symbols are
easier to handle.  And in addition, the documentation could more
truthfully say that setting the user option a non-nil value enables
previews.

Could one of you prepare a patch along those lines, please?
