Well, I don't mind if it is kept, I was just trying to offset the additions.
I understand why removing or replacing samples is generally not a good
idea, but I would point out that in this case, the file could be replaced
without changing the result in any past revision of the test.
This particular test outcome is determined by grepping a line out of the
log that reports the number of errors encountered, and it only has to be
non-zero, so the shorter sample with fewer errors (but at least one) still
passes any old revision.
