Thanks for the answer. Right now I am happy with using erl_parse in the
prototype. I was just baffled by this inconsistency, as I thought the
result would be the same.

I will probably switch to erl_syntax later. I find that I can't push
myself over the threshold of only using erl_syntax, mostly because with
erlide I send the parse trees to Java and there I have to traverse the
tree myself. 

The plan is to move this functionality on the Erlang side, where it
really belongs, and then erl_syntax's API will be perfect.
