Merge branch 'mm/apply-reverse-mode-of-deleted-path'

"git apply --index/--cached" when applying a deletion patch in
reverse failed to give the mode bits of the path "removed" by the
patch to the file it creates, which has been corrected.

* mm/apply-reverse-mode-of-deleted-path:
  apply: set file mode when --reverse creates a deleted file
  t4129: test that git apply warns for unexpected mode changes
