It looks like the strategy would be be to upgrade quotedzputs() to
interact better with nicezputs() and nicechar().  The code that's not
there at the moment is to pick the right sort of quotes, and you only
know that after the event at the moment, so the interface to those two
needs expanding.

I'd propose not bothering to do this in the case where multibyte mode
isn't available (i.e is not even compiled in).  It's not useful enough
and wouldn't get much testing.
