All of the nonincremental-*search-* support folding (except those that use
regexp).

In general, you're correct that most non-regexp searches do char folding.
But that's most, not all. A plain `search-forward' doesn't do folding (by
choice). So we can't just document that "all non regexp searches do
folding".
