git via http proxy

it is supposed to work-like-a-charm - git via a http-proxy - but then again, sometimes it just doesn’t.
in case, changing git clone git://… into git clone http://… does not help this might:

socat TCP4-LISTEN:9418,reuseaddr,fork \
PROXY:proxy.hostname.dom:gitrepo.host.dom:9418,proxyport=3128 &
git clone git://localhost/GITREPOPATH
