In that case why bother? It'll just create a cross-version compatibility
hazard for next-to-no keystroke savings. If the cases were so common
that they could be argued to be sane "default" behavior, I might feel
differently --- but if you were asked in a vacuum what the default
delimiters ought to be, I don't think you'd say "no delimiter".
