{DEC,IBM,MAC}graphics (1 of 2: core)

DECgraphics, IBMgraphics, and MACgraphics used to be recognized when
at least 3 letters were supplied back when they were true boolean
options.  When they got demoted to shortcuts for the symset option,
they started needing 10 (DEC and IBM) or all 11 (MAC), otherwise
triggering "bad syntax in NETHACKOPTIONS" (or config file).  Revert
to having the first three letters be sufficient.
