Hmm, '|' makes quoting mandatory. And the :<allow> is also not that
beautiful IMHO.

What about

[+]|-<class>:<vendor>:<product>:<version>[/[+]|-<class>:...]

? Optional '+' means allow, '-' disallow. An empty field could also
serve as wildcard (instead of explicit -1 which would collide with
disallow).
