I suspect even very-close-to-default configs and some of the examples in
the spec rely on this but I haven't combed through to make sure.
Perhaps the solution is for future Exim 4.x to throw a warning but
continue to operate as if the empty string == 0. Then people's systems
won't break on upgrade, but they'll know they have a possible config
flaw. And we can have a wiki page to document this previously
undocumented feature :-)
