 * 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")

// regex list parser (`makehtml.list`) is left untouched; `makehtml.list` simply
// delegates here when the flag is on.
//
// It differs from the regex parser in the ways CommonMark requires: a change of
// bullet character or ordered delimiter starts a new list, ordered lists keep
// their start number and the `)` delimiter, loose/tight is decided per list (not
// per item), and items nest by content indentation.
