Bug#213718: apt: ignores release tags also

[Gerhard Kroder <gerhard.kroder@t-online.de>]

Package: apt
Version: 0.5.14
Followup-For: Bug #213718

just have done an upgrade of apt from previous testing (sarge) version,
because apt was on hold for a while here. Now next "apt-get upgrade"
wants to upgrade other 193 packages from sarge to sid and doesnt honor
existing (previously working) apt preferences pinning:

Package: *
Pin: release a=testing
Pin-Priority=600

Package: *
Pin: release a=sid
Pin-Priority=100

(no default preference defined  in apt.conf.d)
