Bug#40070: apt does not allow '@' in username for proxy

[Pedro Ivo Andrade Tavares <ptavares@ecp.inf.rdc.puc-rio.br>]

Package: apt
Version: 0.3.7

At my work, I use

export http_proxy=http://user@area:pass@xxx.xxx.xxx.xxx:port/

for enabling use of the company's firewall. (The user database is on an
old Novell server, and everybody has an '@' stuck in its username).

With 0.1.x apt's (as in slink), I could do apt-get update and apt-get
upgrade with no problems.

When I upgraded the machine to potato, I discovered the latest apt
consider "area" as the server, and "pass" as the port, i.e., it stops at
the first "@" character. Please change back to the old behaviour, as now I
can't use it anymore.

Thanks.
