[PATCH] resize, showkey, watchdog, more: Use _exit() instead of exit() in sighandlers

[Marek Polacek]

I've found more inappropriate exit()s in sighandlers.  Here's a patch to
change them into _exit()s.

Oh, and Denys, sorry for the broken tabs/spaces patch.  I've already
slapped myself twice.  This one should be OK.
