Yes, but, why would that be a problem? It's not like we're going to find a
lot of strings 1.2.3-unknown that aren't really version numbers, are we?

Chopping would mean that 2.2.17 and 2.2.17-unknown are equal, but currently
2.2.17-unknown (in epg) is less than 2.2.17.

Certainly the problem can be fixed by wrapping more code with (let
((version-regexp-alist (cons ...)) ...). It's just that it seems a bit
kludgy to me. But whatever, not really a big issue.
