Looks like this broke my setup!

Traceback (most recent call last):
  File "/home/tfarina/depot_tools/clang_format.py", line 70, in <module>
    sys.exit(main(sys.argv[1]))
  File "/home/tfarina/depot_tools/clang_format.py", line 65, in main
    return subprocess.call([tool] + args)
TypeError: can only concatenate list (not "str") to list
No output from clang-format (crashed?).
Please report to bugs.llvm.org.

Which version of Python supports that?

Q: Is using |argv[1]| rather than |argv[1:]| intentional?
I got error following error with Python 2.7.6:

Traceback (most recent call last):
