But it provides no help for applications such as Autoconf that need
backward compatibility.  So I'm neither in favor of options or
builtins changing the behavior of builtins.  Rather I think we should
have another set of builtins.  While you're at it, the new regexp
builtins should drop BRE dead, and use ERE too.
