*sigh*

$ dpkg --compare-versions 1.4-0pre2-1 lt 1.4-1 && echo true || echo false
false

Not to mention that cvs-buildpackage REALLY doesn't like this.

Yes, this works.  And it is currently the only thing that does.

Based on the number of suggestions that I've seen that don't even survive
the dpkg --compare-versions test, clearly SOMETHING needs doing because at
the moment I would surmise that if this list is any indication, half the
project doesn't know how to do it.  I certainly hope this is a case of
silent majority, who does know what works and what doesn't.
