bug#16631: Consideration of title case on case-insensitive matching

[Aharon Robbins]

Hi.

I'm just wondering - does the regex code have the same issue with
title case characters?  This is an issue for gawk.  I will try to run
your test on gawk, but if you have time to check you can do so by
setting GAWK_NO_DFA in the environment and then gawk will bypass the
dfa matcher.

Thanks!
