+* 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.
