gnu sed (there are non-gnu seds Out There) 4.1.5 comes with a manpage
that claims [A-Z] assumes locale C, but a cursory search indicates that
at least SUSv2 requires LC_COLLATE to be used.

Alright, this sounds reasonable but I think that if we expect C locale
then we might as well set LC_ALL=C at the top of our scripts.


(This is just one reason why I certainly will not use en_US locales.)
