Jim, sorry, I cannot. But I'm sure there are enough people who will construct a non-empty
bug report that Falcon sorts against different to ANSI or rest of MySQL . But as we decide
to change how indexes are build anyway, why not to do it in a way that makes NULL special
and uniquely identifiable (for queries where x is NULL) and the sort would conform to
standards at least in some cases. That standard has some strange subtleties is yet another
question.
