   NOTE: The words "todo", "fixme" and "note" should be rendered in a different style
   within comments, match should be caseless (to test for regexp insensitive attribute).
   The regex used for this rule is <endfold id='1'>*/</endfold id='1'>
   String = /\b(?:fixme|todo|note)\b/
   <beginfold id='1'>/*</beginfold id='1'> Thus,  for example "Notebook" is not caught by
   this rule. (the "?:" in the subpattern is there to avoid the regex engine wasting time
   saving a backref, which is not used for anything. I do not know if the overhead of parsing
   that is greater than the time saved by not capturing the text...)
   The rule for catching these words is placed in a context "Comment common", which is used
   by both comment contexts (single line, multiline) using the new "IncludeRules" item.

   Tests for the regex parser.
   It will parse classes, quanitfiers, special characters and regex operaters,
   as specified in the netscape documentation for javascript.
   Regexps are only parsed in their clean form, as the RegExp(string) constructor
   is using a quoted string.
   TODO: Find out if more regex feats should be supported.
         Consider using more itemDatas - assertion, quantifier are options.

   Some tests if the fallthrough works.
   The fallthrough happens if a regexp is not found in a possible (!) position,
   which is after "search(" or "replace(" or "=" or "?" or ":" in version 0.1 of the xml file
