Some minimal amount of folding will nevertheless be necessary even in
asymmetric mode, in order to find character sequences produced by
decomposing characters like ö into o and the combining mark ̈.  That's
because these two characters when juxtaposed (ö) look identical to the
precomposed character on most displays, so we should by default find
such decomposed sequences even when the search string includes the
precomposed character.
