if grass.run_command(...) != 0:
grass.fatal(...)
run_command and write_command return the exit code.
start_command, pipe_command, and feed_command return the Popen object;
you can check its .returncode attribute once it has terminated.
read_command and parse_command return the data written to the child's
stdout; there isn't any mechanism to retrieve the exit status for
these. OTOH, read_command is trivial to implement yourself if you need
this.
