MULTIBYTE has lots of different effects.  The point is we either decide to
turn it on or off; I don't see any point in a special option for this one
very minor case.  zsh is never going to be completely compatible with every
advanced feature of bash, anyway.  So MULTIBYTE almost certainly needs to
be on in that case, but off for POSIX emulation.

I think tracking every possible difference in "sh" and "bash" emulations,
even if they were made separate, would be going way too far.  However, if
we had several dozen more people working on the shell, one of them might
have time to look at it.
