Fix linux regressions, documenting current failures.

A blank line in a log file matches nothing, when combined with grep -v it
matches everything, which means we have had no linux regression testing
since this mistake was made Sept 2017.  Delete the blank lines, and add
current failures to the list with explanations, so we can re-enable regression
testing, and prevent the problem from getting worse.
