Bug#535512: (no subject)

reopen 535512
thanks

aptitude needs to be modified to support /etc/apt/preferences.d, too.  It 
currently calls ReadPinFile and not ReadPinDir.

Actually, I realized after marking this as affecting aptitude that this 
will probably also affect all the APT frontends and bindings in existence.  
(http://google.com/codesearch?q=ReadPinFile and some hand searching finds 
adept, aptitude, debtags, gnome-apt, libept, packagekit, python-apt, 
synaptic, update-manager, update-notifier, plus miscellaneous packages 
that aren’t currently in Debian.)

Perhaps we should think of a way to make this change without requiring 
everyone to start using a new libapt API?
