Re: [PATCH 2/2] Demonstrate merge failure when a directory is replaced with a symlink.

> This test creates two directories, a/b and a/b-2, replaces a/b-2 with a
> symlink to a/b, then merges that change into another branch that
> contains unrelated changes.  Since the changes are unrelated, the merge
> should be free of conflicts, but 'git merge' gives a file/directory
> conflict.
> 
> Note that this test is almost identical to t6035, except that instead of
> replacing a/b with a symlink, it replaces a/b-2 with a symlink.  This
> test results in a merge conflict, whereas t6035 does not.
