+Description: ss: Review ssfilter
+
+The original problem was ssfilter rejecting single expressions if
+enclosed in braces, such as:
+
+| sport = 22 or ( dport = 22 )
+
+This is fixed by allowing 'expr' to be an 'exprlist' enclosed in braces.
+The no longer required recursion in 'exprlist' being an 'exprlist'
+enclosed in braces is dropped.
+
+In addition to that, a few other things are changed:
+
+* Remove pointless 'null' prefix in 'appled' before 'exprlist'.
+* For simple equals matches, '=' operator was required for ports but not
+  allowed for hosts. Make this consistent by making '=' operator
+  optional in both cases.
