[cc65] Bug in CONIO on C128?

I believe I have found a bug in the CONIO library implementation for the
C128.  Attached is a C128 program that uses CONIO to write a menu on the
screen.  In 40-column mode it displays correctly, but in 80-column mode the
text of the menu does not display, instead it draws as unreversed spaces.
 The same code runs in both modes, so there's no tricks here.  You do need
to run from a warm boot (use the 40/80 key to select your mode when booting)
to ensure you are running exactly the same code.

The behavior is the same in both WinVICE and on a real flat C128.

The cputsxy method is what's writing the menu text to the screen and would
be my first place to start looking for the bug.  Uz, if you need the sources
let me know.  They are still very ugly and I don't want to post them to the
mailing list.
