4 The general idea is that we have a single file whose lines come from
5 multiple other files, and those individual files were modified in the same
6 commits. That means that we will see the same commit in multiple contexts,
7 and each one should be attributed to the correct file.
9 Note that we need to use "blame -C" to find the commit for all lines. We will
10 not bother testing that the non-C case fails to find it. That is how blame
11 behaves now, but it is not a property we want to make sure is retained.
