[Distutils] Commands: init'ing booleans to None

[Andrew Kuchling]

There are a bunch of places in distutils.command where Boolean options
are initialized to None; there are other places where they're
initialized to zero.  Is it worth making this consistent, and always
setting them to 0?  (I'm currently going through all the commands
checking the boolean_opts class variables, so I can change the
initializations at the same time.)
