Here's a third attempt with no use of symlinks in the test:
Skip the entire rename/add conflict case if the file added on the
other branch has the same contents as the file being renamed. This
avoids giving the user an extra copy of the same file and presenting a
conflict that is confusing and pointless.
A simple test of this case has been added in
t/t3030-merge-recursive.sh.
