Actually, POSIX says that the behavior of 'echo' is implementation-defined if any of the arguments contain backslash, or if echo's first operand is -n. If the implementation supports the XSI extension, then POSIX defines the behavior of 'echo'. But that extension is not required by POSIX, and many systems don't support it.
