When checking for success or failure of a test, the number of iterations
in the actual test should be irrelevant. As MiniSAT and PicoSAT seem to
disagree on this number, do not check for it, so that the testis pass
again.
Now directly test individual lines with perls regex matching rather than
calling out to grep. Some changes were required:
- escape (, ) if we want to match them
- unescape (, ) if we want to use them as regex bracket groups
- escape +, $ if we want to use them as actual characters
- unescape + to use as a regex +
