The specific error in sparse can (and should) be tested by something
simpler than the script Nil's used to demonstrate the problem. I'll
add the appropriate unittests for this bug to sparse later today.
I'll defer to the optimization people regarding whether to include it
in their battery of tests. Personally, I find that testing against a
few small, but non-trivial real-world data sets is a good thing. The
matrix in question is rather small (9KB) so it's not unreasonable to
include it in the source tree.
