Daniel Kuppitz commented on TINKERPOP-1973:
-------------------------------------------
This is the expected behavior. {{emit()}} is only for intermediate vertices.
You see {{ripple}} because it's the end of the repetition.

gremlin> g.V().repeat(out()).times(2).emit(has('name', 'lop')).path().by('name')

{{emit())) should not be seen as a filter, but rather as an injector.
> Emit predicate ignored after final loop of a RepeatStep with times or until
