argument parsing is not very flexible.. giving no argument to the script makes it crash with:

Traceback (most recent call last):
  File "./format-pull-request.py", line 75, in <module>
    owner, repo = sys.argv[1:3]
ValueError: need more than 0 values to unpack

this should be changed to using some args parsing module, or the builtin getopt function

is by checking out the branch for the pull request:

Hey there,

I'm trying to give this script a test run, but I get the following error message:

Traceback (most recent call last):
  File "./format-pull-request.py", line 14, in <module>
    import requests
ImportError: No module named requests

looks like there's a module that wasn't committed
