+   * Makes a drupalPost() request, using the form submit button's ID.
+   *
+   * Because drupalPost() is silly and doesn't let us choose which button we'd
+   * like to select if multiple buttons have the same value, this function
+   * allows us to select whatever button we'd like based on the ID instead.
+   *
+   * This is done via the absolutely hilarious method of fudging the actual
+   * button labels that don't have the ID we want, so that the only one left
+   * with the correct label is the one with the right ID.
+   *
+   * @see DrupalWebTestCase::drupalPost().
+   *
+   * @param $path
+   *   Location of the post form.
+   * @param $edit
+   *   Field data in an associative array.
+   * @param $submit
+   *   Value of the submit button whose click is to be emulated.
+   * @param $id
+   *   ID of the submit button whose click is to be emulated.
+   * @param array $options
+   *   Options to be forwarded to url().
+   * @param array $headers
+   *   An array containing additional HTTP request headers, each formatted as
+   *   "name: value".
+   * @param null $form_html_id
+   *   (optional) HTML ID of the form to be submitted.
+   * @param null $extra_post
+   *   (optional) A string of additional data to append to the POST submission.
+   *
+   * @return bool|string
+   *   The content from the POST request's curlExec, or FALSE on fail.
