bug#17821: package.el fills files history

[Torsten Wagner]

Hi,
on GNU Emacs 24.3.1
It seems that, whenever package.el installed some packages, the history 
(last couple of visited files) is spammed with files opened during the 
installation process. I believe this is not desired. The history 
function should be turned off just before performing installations and 
turned on after finishing the installation procedure.

Greetings

Torsten
