Martin told Sean,

| You can write that without newlines (valid in GNU sed 3.02) as
|
|   | sed -e '/^$/N; /^\n$/{N; /^\n\n$/D; }'

And as I meant to say when I was making the same suggestion, it would be a
good idea to unset SHELLMETAS temporarily so that the semicolons won't
trigger an unnecessary shell.  (Sean knows that, I realize; I'm pointing
that out for the general readership here.)

 savemetas=$SHELLMETAS # save the value in another variable
 SHELLMETAS # disconnected variable name unsets it
 :0bf
 | sed -e '/^$/N; /^\n$/{N; /^\n\n$/D; }'
 SHELLMETAS=$savemetas # restore original value
