See added testcase 19.c from a bug report. The problem is reading outside the arguments buffers, even though we aren't allowed to. The single can_read_stream variable is not enough, sometimes we need to be able to pop into outer contexts but not into arbitrarily outside contexts. The trick is to terminate argument tokens with a EOF (and not just with 0 that makes us pop contexts), and deal with that in the few places we have to, This enables some cleanups of the can_read_stream variable use.
