This, as others have mentioned, does not belong in ssh.

However, you can very easily do this without creating a wrapper script. 
Just add the following to your .zshrc (or rewrite for other shells):

function ssh()
     /usr/bin/ssh $@[1,-2] ${@[-1]%:}

This will invoke (the real) ssh with all the positional arguments, 
except ":" will be removed from the last argument, if present.

No extra files needed, no wrapper scripts, no measurable performance 
hit, standard ssh software.

Better solution in my book :)
