OK, if we don't make diag x sparse matrices retain the sparsity, then
what method do we have that allows row or column scaling of a sparse
matrix (for example) which preserves sparsity?  The modified version
of dmult did that, correct?  I think that's what Jason was complaining
about (correct me if I'm wrong).
