Hmm... It does make sense, but nobody ever cleans those files up.
Currently, the next run of the test will just overwrite the existing
file or delete it when the test succeeds. So after running the test
suite, you have .out.bad files for every failed test, but not for those
that succeeded.

After this change, won't the test directory accumulate tons of .out.bad
files over time?
