There are valid cases where this could occur, so it might generate a bit of noise.

I have a few questions:
* Does this correctly handle a fix version of "tbd", or "NN-pool" or come other "pseudo" version? Those should be considered matching. 
* When you say ".jcheck/conf" version, what about repos that are configured to use a fix version from the Skara configuration?

I think the main case you want to handle are in repos (e.g., mainline jdk) where the `.jcheck/conf` version is used, and has a value of NN and the JBS mainline fix version has a concrete value of "MM". Anything else seems likely to generate more noise than be hepful.
