A *brief* look at the code suggests not, but I haven't spent time on it.
I could well be wrong - there's a lot of code. I don't have time just
now to actually run a test.
Ordinary lsearch matching does a caseless comparison of keys; it doesn't
force the case. This suggests it isn't expecting its keys to be
case-forced.
Certainly nwildlsearch has a default of caselessness for regex
comparison, but (?-i) should suppress that.
I will do a test when I get a moment.
