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