Bug#231776: /usr/share/man/man8/apt-get.8.gz: add reason for filename difference

[Dan Jacobson <jidanni@jidanni.org>]

Package: apt
Version: 0.5.14
Severity: wishlist
File: /usr/share/man/man8/apt-get.8.gz

       --print-uris
              Instead of fetching the files to install their URIs are printed. Each URI will
              have the path, the destination file name, the size and the expected md5  hash.
              Note that the file name to write to will not always match the file name on the
              remote site!
Here I would mention the reason why saving to the same names is a no-no.
