merge: demonstrate that directory renames can lose local file content
When a directory has been renamed on the local branch and a file has
been added in the old location on a remote branch, we move that new
file to the new location. Unfortunately, if there is already a file
there, we overwrite it with the contents from the remote branch. For
untracked local files, we should probably abort, and for tracked local
files, we should merge the contents. To start with, let's add a test
to demonstrate the breakage. Also note that while files merged in from
a remote branch are normally (and unintuitively) reported as modified,
these files are reported as added.
