multiple array arguments are all flattened instead of getting a nested array

[laggingreflex]

I have a command option like this:

  volume: {
    type: 'array'
  },

So this works as expected:

command --volume some thing

I get an array ['some', 'thing']

But I expect multiple --volume and in that case it doesn't work (as expected):

command --volume some thing --volume some other thing

I get a flattened array ['some', 'thing', 'some', 'other', 'thing']

The expected result is to get an array of arrays, right? Like had the option been a string I'd get either a string (for single argument), or an array of strings for multiple arguments. Similarly I should expect to get either an array, or an array of arrays, no? Why the flattening?

@laggingreflex both new configuration options are out in yargs@6.5.0; there is one bug fix we should make to yargs-parser, but I didn't feel it was severe enough to block the release.
