Description Zac Medico gentoo-dev

Currently, it's possible to choose a package from a lower priority repo due to REQUIRED_USE in a higher priority repo/package, even though the REQUIRED_USE could be satisfied by adjustment of USE. The user should be prompted to adjust USE for the higher priority repo/package, instead of choosing a lower priority repo/package (of the same or lower version).

This should prevent downgrades, but it still won't prevent it from pulling an identical cpv from a lower priority repo:

Hopefully this fixes it, but I haven't written a test case yet:
