I don't think such degree of precision is needed in a section whose
purpose is to describe an option that controls character folding.
With the commands that don't support character folding clearly
identified in the manual where those commands are described (and they
are only mentioned for completeness anyway, as they are not the
recommended ways of performing search), I think the manual strikes the
correct balance between being correct and still easily readable.

Thanks.
