} If printeightbit is set, then nicechar() may pass 8-bit characters,

That may be more consistent, but a bit later on the same function computes
(*swidep = buf + *widthp) so I think what's wanted here is the actual
width rather than the visible width.

} I don't think we need to take account of wide characters here; we don't
} have the information for that in this branch of the code.

I'm more worried about embedded nuls, really, but that should be OK.  I'll
go ahead and commit it as above.
