With finishing touches (mostly updates to in-code comments and log messages). Previous ones were:

Teach "git apply" a similar "-3"way merge fallback option with this series, and you can now apply your patches without having to reduce context. As it will leave the conflicted halves in the index and let you manually resolve conflicts in the working tree, "--3way" implies "--index", and cannot be used with "--cached" or "--reject".

I've been using this in my regular workflow, which involves a fair amount of "git diff >P.diff" later followed by "git apply P.diff" when flipping patches in topics around, and things seem to work OK.

Junio C Hamano (19):
  apply: fix an incomplete comment in check_patch()
  apply: a bit more comments on PATH_TO_BE_DELETED
  apply: clear_image() clears things a bit more
  apply: refactor read_file_or_gitlink()
  apply: factor out checkout_target() helper function
  apply: split load_preimage() helper function out
  apply: refactor "previous patch" logic
  apply: further split load_preimage()
  apply: move check_to_create_blob() closer to its sole caller
  apply: move "already exists" logic to check_to_create()
  apply: accept -3/--3way command line option
  apply: fall back on three-way merge
  apply: plug the three-way merge logic in
  apply: move verify_index_match() higher
  apply: --3way with add/add conflict
  apply: register conflicted stages to the index
  apply: allow rerere() to work on --3way results
  apply: document --3way option
  apply: tests for the --3way option
