matrix-utils: cons called with one argument

[sjamaan]

The matrix-utils egg has two places where it's calling the Scheme cons procedure with only one argument. From the looks of it, there's a y that accidentally got erased (there are two spaces between cons and b):

The above patch has NOT been tested. I don't have the BLAS library installed, so matrix-utils cannot be installed either as it depends on the blas egg.

This was found by Mario's scrutiny run, see http://parenteses.org/mario/misc/specialize-report/install/matrix-utils.html

Fixed in release 1.13 of matrix-utils, thanks for reporting.
