From: Mike Hommey Date: Tue, 21 Apr 2009 05:43:06 GMT Subject: [PATCH v2] Allow git-shell to be used as a ssh forced-command Message-ID: <1240292586-28192-1-git-send-email-mh@glandium.org> In-Reply-To: <20090418063100.GA18568@glandium.org> When using a forced-command, OpenSSH sets the SSH_ORIGINAL_COMMAND variable to what would otherwise be passed to $SHELL -c. When this variable is set and git-shell was given no argument, we use it.
