That's a problem.

I think the grep-using implementation of Jim Knoble *is* better in that
respect both to the existing behavior and to either of the sort-using
suggestions.  It avoids entering the key if it is already in the
authorized_keys file, key restrictions or no key restrictions (although
it does not produce the nice message). If it is not present, it appends
it.
