Whenever there are {reject} rules code is still generated.

In case you have two different constructs that share a prefix and the reject comes first, you get things parsed as the second rule, but pretty printed as the first.

Despite being a bad idea to have grammars of this sort (at least in the example where I found this issue it was), it is still bad that we pretty print things that should not have been parsed in the first place.
