How many bare except: clauses that should be bare are there? To my way
of thinking, requiring the above construct on top of a bare except: is
precisely the kind of wart we wish to encourage in order to *dis*courage
bare except: clauses. In any event, it was Guido's idea to add the 
 except KeyboardInterrupt:
in the first place; I'm simply adding the logical extension. Perhaps
instead of the StandardError idea suggested by others, we should add a
new exception called ExitException that inherits from both SystemExit
and KeyboardInterrupt.
