What I want is a list of changes, and yes/no for regressions.  The
number of regressions does not matter. `piglit/piglit summary console
-d` gives me a list of changes and prints the summary so I can check
if there were regressions.

Another solution I considered was to add an exit status to piglit
summary to indicate whether or not there were regressions.  This would
be the best solution, but I wasn't sure if this would break other
people's use cases.
