Well, while happily hacking away at Cubes 5.1, I found that the program
doesn't deal with Control-Cs.  This is evil.  Furthermore, it won't accept
any attempts to shell out.  This often leaves the player hung, halfway
out of the process, with no possibility of killing it.

I suggest adding the following line to main() in cubes.c:

signal(SIGINT,reallyquit);

This makes the computer ask you "Do you really want to quit?" if you hit
^C, and deals with you intelligently if you say yes.  It saves a lot of
headaches.

If a .signature doesn't follow this line, I'm going to rip out Pnews' innards.
