[net.games.rogue] rogue 5.2 bug fix

defunct (06/21/82)

During fights in 5.2 rogue, there is some garbage printed on the line
at the top of the screen, viz.
 The snake hit--More--&a264c3Y
every once in a while.

The fix for this bug is to replace the entire routine named flush_type()
in mach_dep.c with the following lines:
        struct sgttyb vec;
        ioctl(2, TIOCGETP, &vec);
        ioctl(2, TIOCSETP, &vec);

Ken Arnold, please note.
