Subject: [PATCH] vim: UpdateTmuxEnv function to import SSH_AUTH_SOCK

When a new ssh session to an existing tmux session is opened the
ssh-agent forwarding will use a new SSH_AUTH_SOCK path. This env
variable is updated within the tmux session, but running applications
will need to update it themselves.

Really this should be done automatically.
