Public bug reported:
I'm trying to pin packages from the proprietary graphics drivers PPA,
and I want APT to use this PPA even if a newer version is available in a
target release, so I put it at a pin-priority of 999
--- /etc/apt/preferences.d/graphics-drivers-ppa-pin-999
Package: *
Pin: release o=LP-PPA-graphics-drivers
Pin-Priority: 999
---
If I test this with 'apt-cache policy', the priorities seems to be
correct.

$ apt-cache policy nvidia-346

But if I use the 'APT::Default-Release' configuration option, the
priority gets lowered to 990, resulting in the wrong candidate.

The same thing happens when using apt-get/aptitude's '-t' flag, i.e. the
wrong version gets marked for installation. It seems the policy engine
sets the priority to 990 if the package matches the target release,
regardless of the previous (higher) value. I think this behavior is a
bug and should be fixed so that a certain package's priority doesn't get
lowered for belonging to the target release.
