title: Sending environmental variable with git client when using ssh
body: <p>I would like to be able to send an environmental variable when invoking, for example git clone over ssh:</p>
  
  <p>git clone ssh://host.example/project</p>
  
  <p>I know that this can be achieved by setting the SendEnv in ~/.ssh/config for host.example. Although I would like to avoid modifying any files. For example, with only ssh we could do:</p>
  
  <p>ssh -o SendEnv=MYVAR server.example.com mycommand</p>
  
  <p>and no file modification is necessary. Is there a similar way to achieve this when using git clone over ssh?</p>
  
  <p>Cheers!</p>
