Double enclosed appendable params about argparse HOT 3 CLOSED

It was issue #37 that change the behavior of append.

with nargs='+', all of the positional arguments are collected into an array, and then append 'pushes' this onto the default value ([]), producing the nested arrays. Previously append used concat, but 'push' matches the Python 'append'.

Unless you need to concat the new values to a preexisting array of values, nargs '+' together with the default store action should do the job.

Python argparse produces the same results.

I'd have dig deeper on this, but I don't think that 'append' is meant to work with positional arguments.

A couple of things that work are:

cli.addArgument{['paths'],{nargs: "+"})

and

cli.addArgument(['-p', '--paths'], {action: 'append'})
cli.parseArgs(['-p', 'lib/', '-p', 'examples/'])

The 1st test in positionals.js is the only test derived from python that combines positionals and append.

cli.addArgument(['paths'], {action: 'append'});
cli.addArgument(['paths'], {action: 'append'});

also works (for only 2 items).

Solved. That was ndoc error. Thanks for your advices, Paul.
