[stuff deleted about ^C not generating SIGINT and ^Z not generating SIGSTOP]

How does my name keep ending up at the top of a message with a whole
bunch of leading >>>>'s?  What happened to the names of the people who
actually wrote that stuff?  The only part of this mess that was written
by me is the part about SIGINT and SIGQUIT.  Also, according to the
man page for SIGNAL(3), SIGSTOP is not generated from the keyboard,
SIGTSTP is!

P.S. -- Please stop misquoting me:  The text after the SunOS signal(3) is NOT
WHAT I PUT THERE...arrrgh!
