In emacs editing mode, ksh by default interprets a set 8th bit as

meta prefix, i.e. all characters with the top bit set (>= 0x80) are
taken as commands and cannot be entered literally.

Introduce a new shell option, emacs-usemeta, that allows to toggle
this behavior.  The default is the traditional behavior; to enter
8-bit characters use "set +o emacs-usemeta".
