over the test results.

Example output:

ip1 n        sharp mod_name                                            code      tim

115/391 Test #115: QtCore_qfile_test ...............................***Failed    0.11 sec
        Start 116: QtCore_qflags_test

We will only look for the dotted lines and calculate everything from that.
The summary statistics at the end will be ignored. That allows us to test
this functionality with short timeout values.

Note the field "mod_name". I had split this before, but it is necessary
to use the combination as the key, because the test names are not unique.
