Bug#92358: mention old and new version with "apt-get -s dist-upgrate" [patch]

[Matthijs Melchior <mmelchior@xs4all.nl>]

Package: apt
Severity: wishlist
Version: 0.5.3
Synopsis: mention old and new version with "apt-get -s dist-upgrate" [patch]
Class: change-request

Distribution: Debian testing/unstable
System: Linux 2.4.2-ac3 i686 unknown


Description:
I like to see both the old and new version of a package that is listed
to be upgraded when invoking "apt-get -s dist-upgrate".  This lets me
see where the biggest version differences are, and so decide to do a 
few "apt-get install ..." operations first....

Patch included, this produces lines like:
Inst fileutils [4.0.37-1] (4.0.43-1 Debian:unstable)
