(wilkinson.net is the transmission line unit test)

Actually this is

-0.3333333+ 2.220934E-6* i

vs.

-0.3333333+ 2.220891E-6* i,

far below relative error tolerance. But numdiff does not see it this
way, and does not seem to support complex numbers.

Not sure which result is more accurate. s_param calls blas through gsl,
and results are expected to vary. Just ignore it.

make -k check will run all rests regardless, and autotools provide a
more fancy test harness. I am hesitant to pull in autotools, and I do
not feel inventive.
