lib/util.sh: limit_stderr_cmd (): echo the command like echo_run so that callers don't have to separately call echo_run. this reduces clutter of the nested aliases, ensures that the command is always echoed outside of the inner stderr-limiter (which has a different log_level), and avoids echoing "limit_stderr_cmd" itself as part of the command name.
