If we use an arithmetic operator like ~> then that could be decided
easily.  First we use a rule that all version numbers are decimal (oct
is unlikely), so we simply remove the leading zeros then apply the
rule accordingly, which is >=cat/foo-1.20.3 && <cat/foo-1.20.4.

That would be a good solution since we can also have
'=cat/foo-01.02.3*' to stay as a pure string matcher.
