Hi Linda.

    Hmm....  while the maintainers of sed, said that it was a no-brainer
    to add in another RE engine (like grep) corresponding to the perlRE,
    and said it would be out by August of 2014, I see no version with
    this update nor do I see it mentioned in the latest online documentation.
    
    Does anyone know what happened to this?

It was never completed.  I will look at it.
