New description:

 The documentation for the function norm currently does not mention that
 different kinds of norms are used for complex numbers and vectors of
 complex numbers.

 I was very surprised that for a complex number z,
 norm(z) == norm(vector([z]))^2^, and no hint of this is available from the
 documentation available through executing "sage: norm?".

 See this [http://groups.google.com/group/sage-
 devel/browse_thread/thread/9f941378a95c0191 sage-devel] thread for some
 background information.
