Dot-notation boolean flags aren't parsed correctly

[lasalvavida]

Given the following example:

testScript.js

var argv = require('yargs')
    .options({
        'nested.value': {
            type: 'boolean'
        }
    }).argv;

console.log(argv);

./bin/testScript

{ _: [],
nested: { value: false },
'$0': 'bin\testScript.js' }

./bin/testScript.js --nested.value

{ _: [],
nested: { value: [ false, true ] },
'$0': 'bin\testScript.js' }

The value is placed into an array instead of changing the boolean value.

Did some digging. This was an issue in yargs-parser that is no longer present in master. This can be closed after release.

It would appear that my original assessment was incorrect. This is still a bug in 6.0.0.

var parse = require('yargs-parser');
console.log(parse(
    ['--nested.value'].join(' '),
    {
        boolean : ['nested.value'],
        default : {
            'nested.value' : false
        }
    }
));

{ _: [], nested: { value: [ false, true ] } }

Not specifying that it is a boolean works as a workaround, but this is still a bug.

I would like to work on this. Can anyone help me out a bit?
