Allow script to take multiple paths, and adjust to standard __main__ idiom for cmdline scripts.
Allow script to take multiple paths, and adjust to standard __main__ idiom
for cmdline scripts.

* tools/dev/wc-format.py:
  (usage): remove. all paths are allowed.
  (print_format): move guts of format fetching and printing into this
    function. print 'not under version control' for such a path, rather
    than bailing with USAGE. expand sqlite stuff to use normal pydb idioms
    (eg. execute is not supposed to return anything)
  (__main__): invoke print_format for each path provided
