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
