Humm, this is a problem in the handling of scan rules (less 
powerful than regexp, but much simpler too). The *(ax) 
thing means "optionally, any a or x characters" in the 
rule. If you want (ax), you have to escape ( and ) using 
character match (*[chars]):

'-**[(]ax*[)]*'

(yes, the syntax is a bit twisted)
