Thanks.  In try_run:

This still doesn't quote the arguments to the emulator.
It needs to be quoted enough to get through the command line
parsing that try_run does later.  Or, things need to be
refactored to avoid extra quoting/parsing steps.

The pseudo_emulator still needs to be converted to C, please.
