  38 * SUMMARY: RegExp conformance test
  39 * See http://bugzilla.mozilla.org/show_bug.cgi?id=187133
  40 *
  41 * The tests here employ the regular expression construct:
  42 *
  43 *                   (?!pattern)
  44 *
  45 * This is a "zero-width lookahead negative assertion".
  46 * From the Perl documentation:
  47 *
  48 *   For example, /foo(?!bar)/ matches any occurrence
  49 *   of 'foo' that isn't followed by 'bar'.
  50 *
  51 * It is "zero-width" means that it does not consume any characters and that
  52 * the parens are non-capturing. A non-null match array in the example above
  53 * will have only have length 1, not 2.
  54 *
