As previously discussed, let's flip the switch ^^.
This exposes the problem that it will now be run
for everyone, even if one did not read the help
about the recommended repetition count.
This is not good. So i think we can do the smart thing:
```
$ ./compare.py benchmarks gbench/Inputs/test3_run{0,1}.json
Comparing gbench/Inputs/test3_run0.json to gbench/Inputs/test3_run1.json
Benchmark Time CPU Time Old Time New CPU Old CPU New
--------------------------------------------------------------------------------------------------------
BM_One -0.1000 +0.1000 10 9 100 110
BM_Two +0.1111 -0.0111 9 10 90 89
BM_Two +0.2500 +0.1125 8 10 80 89
BM_Two_pvalue 0.2207 0.6831 U Test, Repetitions: 2. WARNING: Results unreliable! 9+ repetitions recommended.
BM_Two_stat +0.0000 +0.0000 8 8 80 80
```

Or, in the good case (noise omitted):
```
s$ ./compare.py benchmarks /tmp/run{0,1}.json
Comparing /tmp/run0.json to /tmp/run1.json
