Comment(by warner):

 FYI, I had figleaf deltas working for a little while, but the results
 weren't very helpful: they were too easily tricked by insertion/removal of
 lines. If I were going to reimplement this code again now, I would try to
 be more clever. Maybe compare the contents of lines (if you think a line
 has lost coverage, compare it against all lines which have gained
 coverage, and allow identical lines to cancel each other out). Or maybe
 find a clever 'diff' algorithm that spots insertions.

 Also, the report should only show files which have had their coverage
 change. We don't need yet another giant report causing users to have to
 scroll a lot to find the interesting parts.
