_mi_prefix_search() compares end-space against ASCII blank (' ').
It cannot be used for character sets, that do not encode the
blank character like ASCII does. UCS2 is an example. All
character sets with a fixed width > 1 or a mimimum width > 1
cannot represent blank like ASCII does. In these cases we have
to use _mi_seq_search() for the search.
