|  Thomas argued that it is convenient to be able to cut-and-paste the
|  path to a failing testcase. That being said, on balance I agree that
|  it is a bit too noisy to be worth the convenience.

|  
|  Oh dear, it looks like I neglected to add the T11108.stdout to the
|  repository before push. Sorry about that.
|  
|  T8308 on the other hand I am quite perplexed by. This test passes for
|  me. Can you provide the output of,
|  
|      make test TEST=T8308
