Ambiguity in json grammar

 From a correspondent:


<<<<


It is the tests/correct/json.ixml grammar from  
https://github.com/invisibleXML/ixml/blob/master/tests/correct/json.ixml 
with a tiny fix to make it un-ambiguous:


int: "-"?, digit;
      "-"?, onenine, digit+.
(ie replace the digit* with digit+)
