Actually, it's -W; and since changeword will eventually be dropped if m4 2.0 is ever released, no one is relying on it. > > Or generalizing this, a way to pass an arbitrary input fragment directly > on the command line would be nice too.

But we have been issuing a deprecation warning for that since 1.4.7, so it may be worth reusing such a short option in the future. In the meantime, I would not be opposed to the idea via a long option, as it definitely sounds useful. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
