<129136a10c9d37c9cd3d875dfbbd91c452c37554.1621490982.git.gitgitgadget@gmail.com>

In-Reply-To

<pull.859.v3.git.1621490982.gitgitgadget@gmail.com>

From: Elijah Newren <newren@gmail.com>

Add a new testcase where one side of history renames:
   olddir/ -> newdir/
and the other side of history renames:
   olddir/a -> olddir/alpha

   olddir/a -> newdir/a
vs.
   olddir/a -> newdir/alpha
