types for localstorage wrong about vorpal HOT 1 OPEN

I was experiencing this issue (.getItem is not a function). My mistake was assuming that .localStorage("id") retrieved a "channel" object of some type that setItem and getItem could be used on. What it actually does is set the localstorage ID for the entire vorpal instance.

Doesn't work:

...
vorpal.localStorage("test").getItem("t")

> TypeError: vorpal.localStorage(...).getItem is not a function

If you look at the src of the localStorage function:

vorpal.localStorage = function (id) {
  var ls = Object.create(LocalStorage);
  ls.setId(id);
  _.extend(this.localStorage, ls);
  return this;
};

when called it extends the localStorage instance but returns the vorpal instance, meaning that to make that one-liner work, you'd need to access localStorage again after calling it as a function:

vorpal.localStorage("test").localStorage.getItem("t")

Not just returning the localStorage instance is unintuitive for this specific use case, so I assume the function is meant to be used in a setup chain like so:

vorpal
    .delimiter('test$')
    .localStorage("test")
    .show();

vorpal.localStorage.getItem("t")

tl;dr: You can't chain .getItem() or .setItem() onto a localStorage(id) function call

from vorpal.
