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.
