-To pass options to the program that you want to list in GIT_SSH
-you will need to wrap the program and options into a shell script,
-then set GIT_SSH to refer to the shell script.
+`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted
+by the shell, which allows additional arguments to be included.
+`$GIT_SSH` on the other hand must be just the path to a program
+(which can be a wrapper shell script, if additional arguments are
+needed).
 +
 Usually it is easier to configure any desired options through your
 personal `.ssh/config` file.  Please consult your ssh documentation
