Pablo Galindo	e55a0e971b	Fix 'gather' rules in the python parser generator (GH-22021) Currently, empty sequences in gather rules make the conditional for gather rules fail as empty sequences evaluate as "False". We need to explicitly check for "None" (the failure condition) to avoid false negatives.	2020-09-03 15:29:55 +01:00
