Bug#281714: /usr/bin/apt-get: Inappropriate 'Suggested packages' during upgrade

[Andrew Ferrier <andrew@new-destiny.co.uk>]

Package: apt
Version: 0.5.27
Severity: minor
File: /usr/bin/apt-get

I was upgrading from spamassassin 3.0.0 to spamassassin 3.0.1 (and also spamc) 
using:

tracey:/home/ferriera# apt-get install spamassassin spamc

(spamassassin 3.0.1 suggests libnet-smtp-perl OR perl-modules (>= 5.8.0))

I had perl-modules 5.8.4-2.3 installed for some time beforehand.

Nevertheless, during the upgrade, apt printed:

Reading Package Lists... Done
Building Dependency Tree... Done
Suggested packages:
  libnet-smtp-perl
The following packages will be upgraded:
  spamassassin spamc
2 upgraded, 0 newly installed, 0 to remove and 97 not upgraded.
Need to get 0B/817kB of archives.
After unpacking 143kB disk space will be freed.
Reading changelogs... Done
apt-listchanges: Do you want to continue? [Y/n]?

I don't think apt should be suggesting libnet-smtp-perl in these circumstances 
- the perl-modules package already fulfills that.

Thanks,
Andrew.
