+
+	Some fine tuning in regex grammar.
+
+	* parser.y (regex): Empty regex handled by
+	allowing regex to generate empty, rather than
+	a special case production for '/' '/'. Thus
+	empty subexpressions are possible.
+	(regbranch, regterm): Complement is handled
+	in regbranch, so that it has lower precedence
+	than aggregation.
