As hpscdi!jon remarked, two lines of code have been inadvertently
dropped from hack.dog.c, making it more difficult to train your dog.

Fix in hack.dog.c

He also remarked a typo in hack.tty.c. Another player with '@' as kill
character complained about not being able to genocide all @'s. Yes, what
a pity!

Fix in hack.tty.c:

Finally, there was a typo in the routine lookaround() in hack.c that
would cause you to walk into known traps with commands like "fh" or '^H'.
Also, people want to continue eating/digging/counting_their_money even
when a sleeping Leprechaun is nearby. Well, now they can.

Fix in hack.c:
519c515		(in lookaround())
< 			if(x == u.ux+u.dx && y == u.uy+u.dx) goto stop;
---
> 			if(x == u.ux+u.dx && y == u.uy+u.dy) goto stop;
