Here's what I want to know:

1). What sed (vendor, version) does Mac OS X/Darwin use? *BSD or just
really old GNU?


2). Is it "\r" or "\\r" that is really undefined? I was never sure if
"\\" was supposed to be undefined in POSIX (e.g. gnused --posix) or

Hmmm, latest sed.info (4.2.1) says this:

      Note that the only C-like backslash sequences that you can
      portably assume to be interpreted are `\n' and `\\'

Somebody should probably ask Paolo Bonzini. I'll cc him.   :-)

"\r" _is_ undefined, it can be "r" or "CR". "\\r" is not undefined, since it is parsed as "\\" followed by "r".

Even "\n" is undefined on the RHS of the s command.
