The patch and the generated output look correct to me, so

I think it makes sense to add to t4114. Please squash in the test below.

One think to note, though: test 8 (binary -> symlink) shows breakage
with the current master, but test 9 (symlink -> binary) does not.
However, if you run the test under "-d" you can see that the diff has
bogus metainfo. It's just that "apply" doesn't care.

Your test fixes the test failure, and I verified manually that the diff
output is sensible. I don't think an additional test is worth it, but we
could add one that explicitly checks the metainfo if you want to be
extra paranoid.
