[tor-commits] [tor/master] Move the executable part of checkIncludes.py inside an if block.

commit 475749351dcf7a89ad921f120a6daac80310edde
Author: Nick Mathewson <nickm at torproject.org>
Date:   Mon Aug 5 11:30:22 2019 -0400

    Move the executable part of checkIncludes.py inside an if block.
    
    I'll want to make this block into a series of functions in a
    subsequent commit, but I'm doing this separately to get the
    indentation change out of the way.
    
    This branch will end up with making checkIncludes.py an integrated
    part of practracker, for ticket 31176.
