Yum Versionlock validation is wrong

[02strich]

The validation of the name parameter enforces the specification of an epoch, which is not required in RPM as packages do not need to have an epoch value.

I believe it's required, see man yum-versionlock:

   /etc/yum/pluginconf.d/versionlock.list
          The default place to put  package  version  lock  information  (one
          package  and version per. line). The file takes entries in the fol-
          lowing format EPOCH:NAME-VERSION-RELEASE.ARCH See rpm(8)  for  more
          information  on  custom query formats. If the package does not have
          an EPOCH the number will default to 0.

It's good to follow this format otherwise version locking doesn't work or works strange. And I would better not prefix package with default epoch "0:" if missing...

I actually no longer have the test case available which triggered creating this issue, but I believe the last sentence from the quote did not work or did so in an unexpected way. What is you reason for not making the epoch optional (and thereby following RPM)?
