#3149 "eigenvectors" does not show eigenvectors with eigenvalue zero

[Piecewise Linear]

Apparently, one eigenvector is lost below:

(%i1) m: matrix([2,3,1],[4,4,2],[-4,-8,-2]);
[ 2 3 1 ]
[ ]
(%o1) [ 4 4 2 ]
[ ]
[ - 4 - 8 - 2 ]
(%i2) eigenvectors(m);
(%o2) [[[2, 0], [2, 1]], [[[1, 1, - 3]]]]

See bugs #3008 and #3085. The suggested one-line fix to the file eigen.mac mentioned in my response to #3008 seems to correct the problem.
