Bug#852786: apt: inconsitent behaviour with misspelled pkgnames

[lopiuh <lopiuh@gmx.net>]

Package: apt
Version: 1.4~beta4
Severity: minor

Dear Maintainer,

misspelling a pkgname and running apt-get purge for example: apt says
"using CORRECT_PKGNAME" instead, but it is not (purging).
This seems to me as inconsistent output or behaviour

-->prerequirement:
pakage (e.g. openssh-client) is installed
-->detailed steps:
try to purge the pakage and misspell it:
apt purge ssh-server
--> output:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'openssh-client' instead of 'ssh-client'
