Revert "Fix version validation for limits of 1,1."

Abovementioned patch is completely broken. Now e.g. version
validators with min == max == 2 always cause errors for correctly
formed version numbers.
No more patches in this area will be accepted without an autotest.
I also strongly suggest not to throw hard errors anymore for this
kind of thing.
This reverts commit a9f70a366fdc47d58057116ae70c2d20dfa9c5f3.
