Fix the formula for the projection onto the tangent space · e9e6c32c

Sander, Oliver authored 9 years ago

The implemented formula was actually for the projection of Stiefel manifolds, of which
the orthogonal matrices are only a special case. For this special case, one term
drops out and doesn't have to be implemented.
