      9 * SUMMARY: RegExp conformance test
     10 * See http://bugzilla.mozilla.org/show_bug.cgi?id=187133
     11 *
     12 * The tests here employ the regular expression construct:
     13 *
     14 *                   (?!pattern)
     15 *
     16 * This is a "zero-width lookahead negative assertion".
     17 * From the Perl documentation:
     18 *
     19 *   For example, /foo(?!bar)/ matches any occurrence
     20 *   of 'foo' that isn't followed by 'bar'.
     21 *
     22 * It is "zero-width" means that it does not consume any characters and that
     23 * the parens are non-capturing. A non-null match array in the example above
     24 * will have only have length 1, not 2.
     25 *
