I guess this is because -p was considered an argument to -j, but in that case I'd expect to receive an error complaining that -p isn't a number. Similarly, svgtiler -p -j witness.coffee squares_stars.xlsx spews errors because witness.coffee isn't read.
make seems to process non-numeric arguments to -j as normal options or target names instead of swallowing them, which primes my expectations.
