Merge branch 'pw/add-p-recount'
"git add -p" has been lazy in coalescing split patches before passing the result to underlying "git apply", leading to corner case bugs; the logic to prepare the patch to be applied after hunk selections has been tightened. * pw/add-p-recount: add -p: don't rely on apply's '--recount' option add -p: fix counting when splitting and coalescing add -p: calculate offset delta for edited patches add -p: adjust offsets of subsequent hunks when one is skipped t3701: add failing test for pathological context lines t3701: don't hard code sha1 hash values t3701: use test_write_lines and write_script t3701: indent here documents add -i: add function to format hunk header
