I understand his proposal rather as giving
0.005 < 0.039 < 0.05 = 0.050 < 0.5 < 0.39 < 050 < 0.390 < 0.500
I.e. IF (but only if) a part of the version number starts with a zero
the whole is just treated as a decimal number, unlike the current
scheme where we always treat it as two integers separated by a dot (and
leading zeros in a version number part are thus irrelevant currently.)
I don't know which scheme is best. The current one has the advantage
that it is simple and easy to describe, but it can give surprising
results if you think of the version number as an actual *number*.
