* 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.
*
