netnews 2.10.2 visual.c bug

[Rick Adams]

The correct fix is:

***************
*** 1989,1995
  #endif !BSD4_2
  	if (ioctl(2, TIOCGPGRP, (char *)&tpgrp) < 0)
  		goto nottty;
! 	if ((0xffff&tpgrp) != (0xffff&getpgrp(0))) { /* not in foreground */
  		signal(SIGTTOU, SIG_DFL);
  #ifdef BSD4_2
  		sigsetmask(sigblock(0) & ~BIT(SIGTTOU));

--- 1991,1997 -----
  #endif !BSD4_2
  	if (ioctl(2, TIOCGPGRP, (char *)&tpgrp) < 0)
  		goto nottty;
! 	if (tpgrp != getpgrp(0)) { /* not in foreground */
  		signal(SIGTTOU, SIG_DFL);
  #ifdef BSD4_2
  		sigsetmask(sigblock(0) & ~BIT(SIGTTOU));

Do not change them to shorts, leave them ints.
