	/**
	 * Function that returns two types of paths, one relative to symlink, and one
	 * relative to the current working directory. Checks if path is absolute or
	 * relative. If the path is relative, this function checks if the path is
	 * relative to symlink or relative to current working directory. This is an
	 * initiative to find a smarter `srcpath` to supply when building symlinks.
	 * This allows you to determine which path to use out of one of three possible
	 * types of source paths. The first is an absolute path. This is detected by
	 * `path.isAbsolute()`. When an absolute path is provided, it is checked to
	 * see if it exists. If it does it's used, if not an error is returned
	 * (callback)/ thrown (sync). The other two options for `srcpath` are a
	 * relative url. By default Node's `fs.symlink` works by creating a symlink
	 * using `dstpath` and expects the `srcpath` to be relative to the newly
	 * created symlink. If you provide a `srcpath` that does not exist on the file
	 * system it results in a broken symlink. To minimize this, the function
	 * checks to see if the 'relative to symlink' source file exists, and if it
	 * does it will use it. If it does not, it checks if there's a file that
	 * exists that is relative to the current working directory, if does its used.
	 * This preserves the expectations of the original fs.symlink spec and adds
	 * the ability to pass in `relative to current working direcotry` paths.

    // (where we bind to (^|/), or a standalone matchPart context (where
    // we bind to ^, and not /).  Otherwise slashes get duped!
    //
    // In part-matching mode, the start is:
    // - if not isStart: nothing
    // - if traversal possible, but not allowed: ^(?!\.\.?$)
    // - if dots allowed or not possible: ^
    // - if dots possible and not allowed: ^(?!\.)
    // end is:
    // - if not isEnd(): nothing
    // - else: $
    //
    // In full-path matching mode, we put the slash at the START of the
    // pattern, so start is:
    // - if first pattern: same as part-matching mode
    // - if not isStart(): nothing
    // - if traversal possible, but not allowed: /(?!\.\.?(?:$|/))
    // - if dots allowed or not possible: /
    // - if dots possible and not allowed: /(?!\.)
    // end is:
    // - if last pattern, same as part-matching mode
    // - else nothing
    //
    // Always put the (?:$|/) on negated tails, though, because that has to be
    // there to bind the end of the negated pattern portion, and it's easier to
    // just stick it in now rather than try to inject it later in the middle of
    // the pattern.
    //
    // We can just always return the same end, and leave it up to the caller
    // to know whether it's going to be used joined or in parts.
    // And, if the start is adjusted slightly, can do the same there:
    // - if not isStart: nothing
    // - if traversal possible, but not allowed: (?:/|^)(?!\.\.?$)
    // - if dots allowed or not possible: (?:/|^)
    // - if dots possible and not allowed: (?:/|^)(?!\.)
    //
    // But it's better to have a simpler binding without a conditional, for
    // performance, so probably better to return both start options.
    //
    // Then the caller just ignores the end if it's not the first pattern,
    // and the start always gets applied.
    //
    // But that's always going to be $ if it's the ending pattern, or nothing,
    // so the caller can just attach $ at the end of the pattern when building.
    //
    // So the todo is:
    // - better detect what kind of start is needed
    // - return both flavors of starting pattern
    // - attach $ at the end of the pattern when creating the actual RegExp
    //
    // Ah, but wait, no, that all only applies to the root when the first pattern
    // is not an extglob. If the first pattern IS an extglob, then we need all
    // that dot prevention biz to live in the extglob portions, because eg
    // +(*|.x*) can match .xy but not .yx.
    //
    // So, return the two flavors if it's #root and the first child is not an
    // AST, otherwise leave it to the child AST to handle it, and there,
    // use the (?:^|/) style of start binding.
    //
    // Even simplified further:
    // - Since the start for a join is eg /(?!\.) and the start for a part
    // is ^(?!\.), we can just prepend (?!\.) to the pattern (either root
    // or start or whatever) and prepend ^ or / at the Regexp construction.

// Changes from joyent/node:
//
// 1. No leading slash in paths,
//    e.g. in `url.parse('http://foo?bar')` pathname is ``, not `/`
//
// 2. Backslashes are not replaced with slashes,
//    so `http:\\example.org\` is treated like a relative path
//
// 3. Trailing colon is treated like a part of the path,
//    i.e. in `http://example.org:foo` pathname is `:foo`
//
// 4. Nothing is URL-encoded in the resulting object,
//    (in joyent/node some chars in auth and paths are encoded)
//
// 5. `url.parse()` does not have `parseQueryString` argument
//
// 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
//    which can be constructed using other parts of the url.
//

  // Case-insensitive comparison should treat all of them as equivalent.
  //
  // But .toLowerCase() doesn't change ϑ (it's already lowercase),
  // and .toUpperCase() doesn't change ϴ (already uppercase).
  //
  // Applying first lower then upper case normalizes any character:
  // '\u0398\u03f4\u03b8\u03d1'.toLowerCase().toUpperCase() === '\u0398\u0398\u0398\u0398'

/**
 * class MarkdownIt
 *
 * Main parser/renderer class.
 *
 * ##### Usage
 *
 * ```javascript
 * // node.js, "classic" way:
 * var MarkdownIt = require('markdown-it'),
 *     md = new MarkdownIt();
 * var result = md.render('# markdown-it rulezz!');
 *
 * // node.js, the same, but with sugar:
 * var md = require('markdown-it')();
 * var result = md.render('# markdown-it rulezz!');
 *
 * // browser without AMD, added to "window" on script load
 * // Note, there are no dash.
 * var md = window.markdownit();
 * var result = md.render('# markdown-it rulezz!');
 * ```
 *
 * Single line rendering, without paragraph wrap:
 *
 * ```javascript
 * var md = require('markdown-it')();
 * var result = md.renderInline('__markdown-it__ rulezz!');
 * ```

/**
 * new MarkdownIt([presetName, options])
 * - presetName (String): optional, `commonmark` / `zero`
 * - options (Object)
 *
 * Creates parser instanse with given config. Can be called without `new`.
 *
 * ##### presetName
 *
 * MarkdownIt provides named presets as a convenience to quickly
 * enable/disable active syntax rules and options for common use cases.
 *
 * - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.mjs) -
 *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
 * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.mjs) -
 *   similar to GFM, used when no preset name given. Enables all available rules,
 *   but still without html, typographer & autolinker.
 * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.mjs) -
 *   all rules disabled. Useful to quickly setup your config via `.enable()`.
 *   For example, when you need only `bold` and `italic` markup and nothing else.
 *
 * ##### options:
 *
 * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!
 *   That's not safe! You may need external sanitizer to protect output from XSS.
 *   It's better to extend features via plugins, instead of enabling HTML.
 * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags
 *   (`<br />`). This is needed only for full CommonMark compatibility. In real
 *   world you will need HTML output.
 * - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`.
 * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.
 *   Can be useful for external highlighters.
 * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.
 * - __typographer__  - `false`. Set `true` to enable [some language-neutral
 *   replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.mjs) +
 *   quotes beautification (smartquotes).
 * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement
 *   pairs, when typographer enabled and smartquotes on. For example, you can
 *   use `'«»„“'` for Russian, `'„“‚‘'` for German, and
 *   `['«\xA0', '\xA0»', '‹\xA0', '\xA0›']` for French (including nbsp).
 * - __highlight__ - `null`. Highlighter function for fenced code blocks.
 *   Highlighter `function (str, lang)` should return escaped HTML. It can also
 *   return empty string if the source was not changed and should be escaped
 *   externaly. If result starts with <pre... internal wrapper is skipped.
 *
 * ##### Example
 *
 * ```javascript
 * // commonmark mode
 * var md = require('markdown-it')('commonmark');
 *
 * // default mode
 * var md = require('markdown-it')();
 *
 * // enable everything
 * var md = require('markdown-it')({
 *   html: true,
 *   linkify: true,
 *   typographer: true
 * });
 * ```
 *
 * ##### Syntax highlighting
 *
 * ```js
 * var hljs = require('highlight.js') // https://highlightjs.org/
 *
 * var md = require('markdown-it')({
 *   highlight: function (str, lang) {
 *     if (lang && hljs.getLanguage(lang)) {
 *       try {
 *         return hljs.highlight(str, { language: lang, ignoreIllegals: true }).value;
 *       } catch (__) {}
 *     }
 *
 *     return ''; // use external default escaping
 *   }
 * });
 * ```
 *
 * Or with full wrapper override (if you need assign class to `<pre>` or `<code>`):
 *
 * ```javascript
 * var hljs = require('highlight.js') // https://highlightjs.org/
 *
 * // Actual default values
 * var md = require('markdown-it')({
 *   highlight: function (str, lang) {
 *     if (lang && hljs.getLanguage(lang)) {
 *       try {
 *         return '<pre><code class="hljs">' +
 *                hljs.highlight(str, { language: lang, ignoreIllegals: true }).value +
 *                '</code></pre>';
 *       } catch (__) {}
 *     }
 *
 *     return '<pre><code class="hljs">' + md.utils.escapeHtml(str) + '</code></pre>';
 *   }
 * });
 * ```
