looks like a .bat isn't going to work either, so I should probably attempt to do this with a .exe :(

almost everything works, like out.pyz run --all-files works fine and dandy

but running from git commit does not work on windows:

C:\Users\Anthony\workspace\babi>git commit -m "foo"
Traceback (most recent call last):
  File ".git/hooks/pre-commit", line 42, in <module>
    raise SystemExit(subprocess.call(CMD))
  File "C:\Python37\lib\subprocess.py", line 323, in call
    with Popen(*popenargs, **kwargs) as p:
  File "C:\Python37\lib\subprocess.py", line 775, in __init__
    restore_signals, start_new_session)
  File "C:\Python37\lib\subprocess.py", line 1178, in _execute_child
    startupinfo)
OSError: [WinError 193] %1 is not a valid Win32 application

and I feel like that's kinda important :)
