When I try to open an existing spreadsheet this way, it crashes:

  ~ $ google docs edit --title "skijanje"
  Traceback (most recent call last):
    File "/usr/bin/google", line 849, in <module>
      main()
    File "/usr/bin/google", line 835, in main
      run_once(options, args)
    File "/usr/bin/google", line 627, in run_once
      task.run(client, options, args)

    File "/usr/lib/python2.7/subprocess.py", line 1326, in _execute_child
      raise child_exception
  OSError: [Errno 2] No such file or directory

I guess I was expecting some magic, i.e. a spreadsheet automatically converted to/from CSV or YAML. :)
