In addition to the zero/non-zero convention, there are:

- A process killed by a signal exits with 128+$signal.  That's why
  Lawrence guessed the <130> was the exit code (130-128 is SIGINT)..

- There's sysexits.h, but not everyone uses it.  However, one could
  argue that zsh should recognize those and print messages similar to
  the messages it prints for processes killed by signals.
