 Hi Brett!
 
 Thanks for analysing this and for the patch.
 
 I tried fileobj with this, and I still see some weirdness (but perhaps
 that is what you meant with the colour pair 0 question?):
 
 When running `fileobj /bin/ls`, the values have three colors: green,
 blue, black. The green and blue ones work fine. When I move the curses
 over one of the black one, it becomes black-on-green (fine) but when I
 move the cursor off, it becomes grey-on-black instead of the
 black-on-white it was before.
 
 My terminal is black-on-white by default in case it matters.
 
 As for the patch itself: The color part should be fine to upstream,
 since ncurses chgat(3) also documents PAIR_NUMBER. However, I can't
 find __ATTRIBUTES in the ncurses man pages nor headers. Is there a
 different way to get that?
 
 Cheers,
  Thomas
