Not sure, but could it be that in some cases the output of test failures is 
there, but chopped off since CRAN displays the 13 line tail? At least that's 
what I've experienced, and reported, and asked to be increased in the past. 
Often the first error causes a cascade, so it's the head you need to see, not 
the tail. If I've got that right, how about a much larger limit than 13, say 
1000. Or the first 50 and last 50 lines of output.
