--- Comment #4 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
According to:

http://pubs.opengroup.org/onlinepubs/009695399/utilities/sed.html

[In a replacement] the meaning of a '\' immediately followed by any character
other than '&', '\', a digit, or the delimiter character used for this command,
is unspecified.

So I think that rules out all the normal escaped characters.
