This patch allows an argument that matches the regex /\-\d/ not to be recognized as an "option" and treated as an "argument" instead. Normally this does not work unless you set the options-first (--) parameter before the argument in question. Since options do not normally start with a number, this provides a simple fix to this common problem.
For example if one has a Docopt entry:
rectangle <x1> <y1> <x2> <y2>
This will not work if any of the arguments are negative numbers since the negative number would be treated as an option.
The only solution would be:
rectangle -- <x1> <y1> <x2> <y2>
which is inconvenient.
The following simple patch fixes this issue.
In Docopt.java:
`455a456,458
if(tokens.current().matches("^\\-\\d"))
parsed.add(new Argument(null, tokens.move()));
else
`
