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
