There are tests for matrix multiplication, just not one for this
particular path through the code which is scalar multiplication by a row
vector. (This is the optimized _dotblas.c code by the way which was
just changed in 0.9.5 to try and make it faster -- obviously some bugs
crept in at the same time). But, these bugs were quickly fixed when
they were made apparent.
That's why we are still not at 1.0 yet.
Feel free to contribute more tests.
