Use httpconnection even with proxies. This should give us HTTP keepalive when we talk to proxies and should allow us to stream a file in unbundle (instead of reading everything into a string). This should fix issue376.

#!/bin/sh

hg init
echo This is file a1 > a
hg add a
hg commit -m "commit #0" -d "1000000 0"
touch b
hg add b
rm b
hg commit -A -m"comment #1" -d "1000000 0"
