This is Library Working Group issue 1337, which is still open but has
got five votes for Tentatively Ready on the lib reflector ... and it's
obviously right!

Tested x86_64-linux (and Solaris by Rainer) - committed to trunk.

	PR libstdc++/45990
	* include/bits/regex.h (regex_traits::isctype): DR 1337.
