>> Hi folks.  Is this a bug?  When I use %S%s to make the RPROMPT inverse video, zsh leaves a space at the end.  Without inverse video, it is flush with the margin.  Is it possible that the calculation to figure out at which column to start the RPROMPT is not taking into account that %s is non-printing?
