/*
 *
 * Date:    06 January 2003
 * SUMMARY: RegExp conformance test
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=187133
 *
 * The tests here employ the regular expression construct:
 *
 *                   (?!pattern)
 *
 * This is a "zero-width lookahead negative assertion".
 * From the Perl documentation:
 *
 *   For example, /foo(?!bar)/ matches any occurrence
 *   of 'foo' that isn't followed by 'bar'.
 *
 * It is "zero-width" means that it does not consume any characters and that
 * the parens are non-capturing. A non-null match array in the example above
 * will have only have length 1, not 2.
 *
