description:
Pull up following revision(s) (requested by nakayama in ticket #755):

        external/bsd/mdocml/include/config.h: revision 1.5
        external/bsd/mdocml/dist/term_ascii.c: revision 1.2

Re-enable wchar_t support.  mandoc(1) can now fall back to ascii
output if the locale is non-UTF-8 locale with the following change.

https://marc.info/?l=openbsd-cvs&m=152364416720474
Modified files:
usr.bin/mandoc : term_ascii.c
Log message:
Make sure that mandoc only goes into UTF-8 mode if the user really
selected UTF-8, not some other multibyte locale.  This obviously
makes no difference on OpenBSD but improves portability.
Issue reported by <Nakayama at NetBSD> via wiz@.
