I hacked up a quick Perl script and no character in any of the ranges
changes if I apply Perl's lc or uc function (but before your fix it
reports problems).

I said I was leaning towards backporting this to 1.4.x, but having looked
into it I think that's not a good idea as it would result in some
queries no longer matching unless the affected documents were reindexed.
