An EOL quadrigraph sounds better to me for this particular problem.

But surely it wouldn't merely be an EOL quadrigraph: it would be a
quadrigraph standing for the empty string.  So I suggest using @""@ as
the quadrigraph, and having it always expand to nothing.  This might
be useful in places other than at end of line.
