When we started multibyte support, traditional sh's all only supported
the portable character set, so we let zsh behave as if characters were
all 8 bit as the least disruptive change.  Multibyte is on in all other
emulations, even ksh.

With multibyte character sets virtually universal, it's probably time to
assume obeying the localization screws things up least.

With MULTIBYTE always on when available, the "EMULATE" flag becomes
redundant.
