Bug#47555: apt sends \015 as line terminator in http requests, not \015\012

[Peter Nagy <pnagy@bunwss04nok.europe.nokia.com>]

Package: apt
Version: 0.3.13

Spec says that everyone must send \015\012 as line terminator,
and receivers should be graceful and accept \015, too.
Apparently our proxy is not graceful, and treats the whole
request as one (still unfinished) line. So apt-get just waits
for answer that never comes - as the proxy is still parsing the
first line.
