Subject: [PATCH] GIT_SSH alternate ssh name or helper
Message-ID: <20050803151542.GA6655@medusa>

This patch make possible to use alternate ssh binary or ssh helper
script. The script can be used to give additional parameters to ssh
binary (like private key, protocol version, ...).

Example script could look like this:

#!/bin/sh
ssh -1 -i myprivatekey.key "$@"

The patch itself is realy very simple:
