I'm not saying that texi2any doesn't play by the locale's rules.
Quite the contrary: I'm saying that _if_ it plays by the locale's
rules, then downcasing an innocent word like "INIT" will yield "ınit"
in Turkish locale, something that could well be unexpected, and if you
compare thatr with "init" for equality, it will compare not equal.
