The gitattributes documentation claims that the pattern
rules are largely the same as for gitignore. However, the
rules for recursion are different.

In an ideal world, we would make them the same (if for
nothing else than consistency and simplicity), but that
would create backwards compatibility issues. For some
discussion, see this thread:

  https://public-inbox.org/git/slrnkldd3g.1l4.jan@majutsushi.net/

But let's at least document the differences instead of
actively misleading the user by claiming that they're the
same.

Fix for a commented-out code to adjust it to a rather old API change.

* ys/bisect-object-id-missing-conversion-fix:
  bisect: debug: convert struct object to object_id

When resetting the working tree files recursively, the working tree
of submodules are now also reset to match.

* sb/submodule-update-reset-fix:
  submodule: submodule_move_head omits old argument in forced case
  unpack-trees: oneway_merge to update submodules
  t/lib-submodule-update.sh: fix test ignoring ignored files in submodules
  t/lib-submodule-update.sh: clarify test

"git commit --fixup" did not allow "-m<message>" option to be used
at the same time; allow it to annotate resulting commit with more
text.

* ab/commit-m-with-fixup:
  commit: add support for --fixup <commit> -m"<extra message>"
  commit doc: document that -c, -C, -F and --fixup with -m error

"git status" after moving a path in the working tree (hence making
it appear "removed") and then adding with the -N option (hence
making that appear "added") detected it as a rename, but did not
report the  old and new pathnames correctly.

* nd/ita-wt-renames-in-status:
  wt-status.c: handle worktree renames
  wt-status.c: rename rename-related fields in wt_status_change_data
  wt-status.c: catch unhandled diff status codes
  wt-status.c: coding style fix
  Use DIFF_DETECT_RENAME for detect_rename assignments
  t2203: test status output with porcelain v2 format

Doc update.

* ab/doc-cat-file-e-still-shows-errors:
  cat-file doc: document that -e will return some output

Doc update.

* as/read-tree-prefix-doc-fix:
  doc/read-tree: remove obsolete remark

"git add -p" was taught to ignore local changes to submodules as
they do not interfere with the partial addition of regular changes
anyway.

* nd/add-i-ignore-submodules:
  add--interactive: ignore submodule changes except HEAD

"git stash -- <pathspec>" incorrectly blew away untracked files in
the directory that matched the pathspec, which has been corrected.

* tg/stash-with-pathspec-fix:
  stash: don't delete untracked files that match pathspec
