- for some reason, docopt insists on regluing together the command line then resplitting.
  To temporarily fix support for command lines like: `--test="a b c"`, we rejoin with "\t" and tokenizer via \t when parsing the command line.
- fix issue with --long="test a b c"

Docopt was rejoining argv and then resplitting based on """\s+""".  Don't do this anymore...
