In order to allow kegs built with the same version but differing formula revisions to coexist, we must encode the revision as part of the keg's name. This is necessary to actually perform an upgrade, as we cannot upgrade a keg in-place, and temporarily moving it pending the result of the upgrade is error-prone and potentially slow. To accomplish this, we introduce a new Formula#pkg_version method that concatenates the active_spec version with the formula revision. An exception is made for a formula that has no revision: the tag is omitted. This preserves compatibility with existing installations.
