pacman magic passage bug fixed
There's a bug in the distributed pacman which allows the monsters
to get one free move as they go through the magic passage.  This
caused me great pain until I fixed it, as I often get chased
through there.  The fixes are as follows.

Add to pacdefs.h:

#define	xleft(x)	((x)+LEFTINT>=0?(x)+LEFTINT:XWRAP)
#define	xright(x)	((x)+RIGHTINT<=XWRAP?(X)+RIGHTINT:0) THESE + < MONSTER.C: NEWX="tmpx" TO CHANGES THEN, --- 108C108 MAKE LEFTINT;> 			newx = xleft(tmpx);
110,111d109
 			newx = xright(tmpx);
117,118d114
= XWRAP)
 		default:
> 			errgen("bad which");
> 			break;

 		((next = brd[y+DOWNINT][x]) != WALL) &&
206c203
 		((next = brd[y][xleft(x)]) != WALL) &&
212c209
 		((next = brd[y][xright(x)]) != WALL) &&
234,235c231,232
 				if (((next = brd[y+DOWNINT][x]) != WALL) &&
> 					(next != GATE))
242,243c239,240
 				if (((next = brd[y+UPINT][x]) != WALL) &&
> 					(next != GATE))
250,251c247,248
 				if ((next = brd[y][xleft(x)]) != WALL &&
> 					(next != GATE))
258,259c255,256
 				if ((next = brd[y][xright(x)]) != WALL &&
> 					(next != GATE))
