Even if the 2 paths did have matching content at one point? In fact,
the 2 files here get added with identicaly content and one of them is
later modified...

In this case, if you use the common part (100%) as the ancestor, then
you get a _clean_ merge. The file is added on both sides identically,
and then it changes on one side.
