Different than GNU is not a bug.

I have 7.3 here.  It behaves as the above, which is how the man page says it
should work.  The following is how the man page specifies you can substitute
a newline, by prefacing a quoted actual newline with a backslash:

$ echo axa | sed 's/x/\
> /g'
a
a

  That's how I remember classic sed behaving (Unix v7 or thereabouts.)
