`need-args' accept a command in one argument, and extra arguments
to that command in the remaining arguments.  If no extra arguments
are provided, the command is not run, otherwise it is.

This is useful in combination with Posix `xargs', which doesn't have
the nice GNU option `--no-run-if-empty' (`-r').
