    /**
     * Tag-closer extension for CodeMirror.
     *
     * This extension adds an "autoCloseTags" option that can be set to
     * either true to get the default behavior, or an object to further
     * configure its behavior.
     *
     * These are supported options:
     *
     * `whenClosing` (default true)
     *   Whether to autoclose when the '/' of a closing tag is typed.
     * `whenOpening` (default true)
     *   Whether to autoclose the tag when the final '>' of an opening
     *   tag is typed.
     * `dontCloseTags` (default is empty tags for HTML, none for XML)
     *   An array of tag names that should not be autoclosed.
     * `indentTags` (default is block tags for HTML, none for XML)
     *   An array of tag names that should, when opened, cause a
     *   blank line to be added inside the tag, and the blank line and
     *   closing line to be indented.
     *
     * See demos/closetag.html for a usage example.
