Interestingly, ${(V)...} et al. don't consult iswprint(), they just
call wcs_nicechar_sel() which only consults WCWIDTH().
Some characters like $'\u21A9' report and occupy a width of 1, but
part of the character overlaps the cell to the right when displayed.

Suggest a patch to Src/wcwidth9.h ? I'm not sure whether to update
the static wcwidth9() function, or the entries in the lookup tables.
