"printf" (in POSIX) accepts a %b specifier to emulate old-fashioned
echo.  So all the behaviors are available:

	bash        POSIX sh

	echo        printf '%s\n'
	echo -n     printf '%s'
	echo -e     printf '%b\n'
	echo -ne    printf '%b'

Of course this is orthogonal to the question of which one the LSB
init functions should use.  I have no opinion on that.
