Bug#352583: apt-cache: new option to show package versions

["Nelson A. de Oliveira" <naoliv@gmail.com>]

Package: apt
Version: 0.6.43.2
Severity: wishlist

Hi!

Today I was trying to see the available versions of a package. With
"apt-cache madison aptitude", for example, I get:

  aptitude | 0.4.1-1experimental1 | http://ftp.debian.org experimental/main Packages
  aptitude |    0.4.1-1 | http://ftp.debian.org unstable/main Packages
  aptitude |    0.4.1-1 | http://ftp.debian.org unstable/main Sources
  aptitude | 0.4.1-1experimental1 | http://ftp.debian.org experimental/main Sources

However, on a machine without source URLs on sources.lists, I get:

E: You must put some 'source' URIs in your sources.list

The behavior that I was expecting is something like
"apt-cache show aptitude | grep Version"

Maybe an "apt-cache version package" could be implemented.

Using this, we can see the available versions, even with the users that
don't have some source URL on their sources.list file.

Thank you very much!

Nelson
