* Fixed a bug that I introduced in fgWarning()/fgError(): I thought that

((a) || (b)) was defined to have value as:
     (a) if (a) != 0
     (b) if (a) == 0

   ...instead, it has value 0/1.  This was causing a bug.  It's probably
   just as well, since what I was trying to do definitely fell into the
   category of "clever code" rather than "clear code".

   Sorry.

 * Made glutSetKeyRepeat() call fgError() if you go out of range.  (The
   old code silently did nothing---not even a warning.)

   If it is really desirable to keep running, we should probably at least
   generate an fgWarning().

 * Deleted some say-nothing-new comments.

 * XXX added: Is glutSetKeyRepeat() deprecated?
