Bug#195510: [libapt-pkg] apt-get -s remove displays candidate version - also breaks on tristate upgrade path

[browaeys.alban@wanadoo.fr]

Does this fix all issues in :
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=204780
if so could they be merged ?


ALso could it explain this upgrade path which is broken in
current apt (even apt 0.6):

installed:
"foo1" contains header.h
"bar1" does not contains headers.h

installing "x":
"x" depends on "bar2"
"bar2" contains header.h
"foo2" does not contains header.h

processing installation:
apt install "x" and "bar2" : this breaks on "bar2" trying to
overwrite header.h from "foo1".
Upgrade stop .(sometimes foo2 is upgrade first i guess it
depends on the ordering, in this case everything works well)

Retrying to upgade:
"x" is in broken state . apt try to resolve the problem before
anything.
One have to dpkg -i foo2 else apt is stuck.
