New description:
Fix vector normalization so that it agrees with the standard definition of
normalizing a vector. Right now it divides the entries of the vector by
the first nonzero entry of the vector. For instance:
{{{sage: v = vector([1,2,3])}}}
{{{sage: v.normalize()}}}
{{{(1, 2, 3)}}}
Shouldn't the default implementation be the Euclidean norm? Especially
since v.norm() returns the Euclidean norm.
