 * It will also avoid "<interrupt>" being displayed when ^Y is pressed.
 *
 * Otherwise, the VMS SMG calls will be used.  These calls block use of
 * the escape key, as well as certain control keys, so gameplay is not
 * the same, although the differences are fairly negligible.  You must
 * then use a VTxxx function key or two <escape>s to give an ESC response.

 * to prompt the player for a command to spawn in order to respond.  The
 * latter capability will not be available if SHELL is disabled below.
 * If you undefine MAIL, broadcasts will go straight to the terminal,
 * resulting in disruption of the screen display; use <ctrl/R> to redraw.

 * SHELL enables the player to 'escape' into a spawned subprocess via

 * If the player attaches back to NetHack, then a subsequent escape will
 * re-attach to the existing subprocess.  Any such subprocess left over
 * at game exit will be deleted by an exit handler.
 * SUSPEND enables someone running NetHack in a subprocess to reconnect
 * to the parent process with the <ctrl/Z> command; this is not very
 * close to Unix job control, but it's better than nothing.
