Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case, there are 136 comparisons, you can thus
expect the following amount of false-positive results:
  6.80 false positives, when considering a   5% risk acceptance (*, **, ***),
  1.36 false positives, when considering a   1% risk acceptance (**, ***),
  0.14 false positives, when considering a 0.1% risk acceptance (***)

We only want to keep the first 10 lines, we can give up splitting the string at the 11th line.
