[Bug 2086623] [NEW] apt-get install does not downgrade packages with -t

[Jarno Suni]

Public bug reported:

Suppose package x has greater version than the latest one in
repositories.

sudo apt-get install -t=$(lsb_release -cs) x

does not downgrade the package, but

sudo apt-get install x/$(lsb_release -cs)

does.

I don't see why it shouldn't downgrade by the first command, too.

Besides, I request an option to retain package's auto/manual state in
this operation.
