Bug#732628: Please support squid-deb-proxy-client

[Michael Vogt <mvo@debian.org>]

Package: debootstrap
Version: git

It would be nice if deboostrap would support the proxy auto discovery
from apt-get. Attached is a patch that adds it, please let me know if
that sounds reasonable and if the patch looks ok. Happy to adjust it
if you have any suggestions.

Cheers,
 Michael
