Merge branch 'jc/apply-reject-noop-hunk'

"git apply" cannot diagnose a patch corruption when the breakage is to mark the length of the hunk shorter than it really is on the hunk header line "@@ -l,k +m,n @@"; one special case it could is when the hunk becomes no-op (e.g. k == n == 2 for two-line context patch output), and it learned how to do so. * jc/apply-reject-noop-hunk: apply: reject a hunk that does not do anything
