/**
 * matchRecursiveRegExp
 *
 * (c) 2007 Steven Levithan <stevenlevithan.com>
 * MIT License
 *
 * Accepts a string to search, a left and right format delimiter
 * as regex patterns, and optional regex flags. Returns an array
 * of matches, allowing nested instances of left/right delimiters.
 * Use the "g" flag to return all matches, otherwise only the
 * first is returned. Be careful to ensure that the left and
 * right format delimiters produce mutually exclusive matches.
 * Backreferences are not supported within the right delimiter
 * due to how it is internally combined with the left delimiter.
 * When matching strings whose format delimiters are unbalanced
 * to the left or right, the output is intentionally as a
 * conventional regex library with recursion support would
 * produce, e.g. "<<x>" and "<x>>" both produce ["x"] when using
 * "<" and ">" as the delimiters (both strings contain a single,
 * balanced instance of "<x>").
 *
 * examples:
 * matchRecursiveRegExp("test", "\\(", "\\)")
 * returns: []
 * matchRecursiveRegExp("<t<<e>><s>>t<>", "<", ">", "g")
 * returns: ["t<<e>><s>", ""]
 * matchRecursiveRegExp("<div id=\"x\">test</div>", "<div\\b[^>]*>", "</div>", "gi")

// GFM "disallowed raw HTML" extension (tagfilter): a small blacklist of HTML tags
// is neutralized in the output by escaping their leading `<` to `&lt;`. These tags
// are singled out because they change how the surrounding markup is interpreted
// (script/style/iframe/etc.). See https://github.github.com/gfm/#disallowed-raw-html-extension-
//
// When the `safeMode` option is on, this stage also neutralizes a broader set of
// dangerous raw-HTML tags Showdown never generates and strips inline event-handler
// attributes (on*=...), so that embedded `<script>`, `<img onerror>`, `<svg onload>`
// and similar cannot execute. This is defense-in-depth, not a full HTML sanitizer.

// GFM task-list item renderer, shared by both list parsers.

// Given the raw text of a single list item, it matches a leading `[ ]`/`[x]`
// marker plus the rest of that line and renders the marker as a disabled
// `<input type="checkbox">`, leaving the line's text in place for the caller to
// parse further. It runs at the same (raw, pre-parse) stage in both
// `makehtml.list` (the default regex parser) and `makehtml.cmList` (the
// commonmark container-block parser), so the events below always expose the
// task item's raw source line on either path.
//
// Events (nested under the `makehtml.list.taskListItem` namespace that the default
// list parser already uses for its item-level events):
//   makehtml.list.taskListItem.checkbox.onCapture - fired on a matched task line.
//     `input` and `_wholeMatch` are the full source line (`[ ] foo *bar*`);
//     `attributes` are the checkbox attributes. Returning output overrides the line.
//   makehtml.list.taskListItem.checkbox.onHash    - fired with the rendered line
//     (`<input ...> foo *bar*`) before it is handed back to the caller.
