Allow to strip dashes from options in result dictionary

From the project README:

The return value is a simple dictionary with options, arguments and commands as keys, spelled exactly like in your help message.

options['--file'] looks too odd though. That would be great if a user could invoke docopt with additional named parameter:

options = docopt(__doc__, strip_dashes=True)

So that result dictionary has no leading dashes, which is equivalent to:

def strip_dashes(options):
    return {k.lstrip('-'): v for k, v in options.items()}

options = strip_dashes(docopt(__doc__))

Will you accept pull request for this feature?

Had the same issue. I’m using this one liner: args = {arg.lstrip('-') : value for arg, value in docopt(__doc__).items()}

Coming back to post it here, I realised @pavel-paulau has basically the same thing in his original post.

@dmwelch let me know if docopt-dispatch solves your problem. If it gets popular I will integrate it into docopt.
