Do not send a connection: keep-alive, at all
Vietnamese updated by Tran Ngoc Quan. Closes: #717016
Merge remote-tracking branch 'donkult/debian/sid' into debian/sid
fix if-clause to generate hook-info for 'rc' packages (Closes: 717006)
Merge remote-tracking branch 'geissert/proxy-keep-alive' into debian/sid
skip all Description fields in apt-cache, not just first

Given a Packages file like:
[…]
Description: foo bar baz
 moo moo moo
Multi-Arch: foreign
Description-md5: 97e204a9f4ad8c681dbd54ec7c505251
[…]

We have to display the Multi-Arch flag field as well as the fields
after the Description-md5, but not this field itself, as we already
have one printed alongside the Description we display.
