listener does not work for subtopics

[mhkabir]

Listener does not seem to know about the subtopics like vehicle_vision_position, presumably because the generator is not parsing this line from the message file :

...
# TOPICS vehicle_local_position vehicle_local_position_groundtruth vehicle_vision_position

pxh> listener vehicle_vision_attitude
 Topic did not match any known topics
pxh> listener vehicle_local_position_groundtruth
 Topic did not match any known topics
