   Please tell us the results which BSD sed produces.  I want to
   check whether this is a bug, an imcompatibility, or a non-POSIX
   expression.  BTW, do you know by chance the maintainer of BSD
   sed?

The BSDs maintain by architecture, not by application.  Since sed
is not architecture specific, you would have to propose a modification
to the base system of the respective BSD branch.  If your problem
is with the sed shipping with MacOSX, you would probably need to
submit a bug to the Darwin development team.
