Description (last modified by aaugustin)

Not sure if this is a bug.

I was attempt to construct a Q object that wouldn't ever match anything (an API calls for a Q object to be returned, but certain situations call for nothing to be matched by it). I initially figured ~ Q() would do the trick, but that matches everything, just like a plain Q().

(I ended up using Q(pk__isnull=True), which is a hack but seems to be OK.)

Haven't dug into what would be required to make this work, but presuming it can be reasonably implemented this seems sensible.
