*
* If `options.hash` is `true`, returns an object of key/value pairs
* instead (where keys are control names).
* <h4>The Options</h4>
*
* The options allow you to control two things: What kind of return
* value you get (an object or a string), and whether and which `submit`
* fields are included in that object or string.
*
* If you do not supply an `options` object _at all_, the options
* `{hash: false}` are used.
*
* If you supply an `options` object, it may have the following options:
* - `hash` ([[Boolean]]): `true` to return a plain object with keys and values
* (not a [[Hash]]; see below), `false` to return a String in query string
* format. If you supply an `options` object with no `hash` member, `hash`
* defaults to `true`. Note that this is __not__ the same as leaving off the
* `options` object entirely (see above).
* - `submit` ([[Boolean]] | [[String]]): In essence: If you omit this option the
* first submit button in the form is included; if you supply `false`,
* no submit buttons are included; if you supply the name of a submit
* button, the first button with that name is included. Note that the `false`
* value __must__ really be `false`, not _falsey_; falsey-but-not-false is
* like omitting the option.
*
* _(Deprecated)_ If you pass in a [[Boolean]] instead of an object for `options`, it
* is used as the `hash` option and all other options are defaulted.
*
* <h4>A <em>hash</em>, not a Hash</h4>
*
* If you opt to receive an object, it is a plain JavaScript object with keys
* and values, __not__ a [[Hash]]. All JavaScript objects are hashes in the lower-case
* sense of the word, which is why the option has that somewhat-confusing name.
