Here are the topics that have been cooking.  Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.

The tip of the 'master' branch has passed v2.0.0-rc1.  Last minute
fixes to newly added code keep flowing in, which is good.  I've
picked up some topics that will not be part of the upcoming release
to 'pu' not to lose them, but I didn't have time to give them a deep

You can find the changes described here in the integration branches
of the repositories listed at

 - CodingGuidelines: give an example for shell function preamble
 - CodingGuidelines: give an example for control statements
 - CodingGuidelines: give an example for redirection
 - CodingGuidelines: give an example for case/esac statement

 - merge-recursive: -Xindex-only to leave worktree unchanged
 - merge-recursive: internal flag to avoid touching the worktree

 (this branch is used by tr/remerge-diff.)

 Will hold.

* tr/remerge-diff (2014-02-26) 5 commits
 . log --remerge-diff: show what the conflict resolution changed
 . name-hash: allow dir hashing even when !ignore_case
 . merge-recursive: allow storing conflict hunks in index
 . revision: fold all merge diff variants into an enum merge_diff_mode
 . combine-diff: do not pass revs->dense_combined_merges redundantly
 (this branch uses tr/merge-recursive-index-only.)

 "log -p" output learns a new way to let users inspect a merge
 commit by showing the differences between the automerged result
 with conflicts the person who recorded the merge would have seen
 and the final conflict resolution that was recorded in the merge.

 Needs to be rebased, now kb/fast-hashmap topic is in.

* jk/makefile (2014-02-05) 16 commits
 - move LESS/LV pager environment to Makefile
 - Makefile: teach scripts to include make variables
 - Makefile: auto-build C strings from make variables
 - Makefile: drop *_SQ variables
 - Makefile: add c-quote helper function
 - Makefile: introduce sq function for shell-quoting

 - Makefile: use tempfile/mv strategy for GIT-*
 - Makefile: introduce make-var helper function
 - Makefile: fix git-instaweb dependency on gitweb
 - Makefile: drop USE_GETTEXT_SCHEME from GIT-CFLAGS

 Simplify the Makefile rules and macros that exist primarily for
 quoting purposes, and make it easier to robustly express the
 dependency rules.

 Expecting a reroll.

* po/everyday-doc (2014-01-27) 1 commit
 - Make 'git help everyday' work

 This may make the said command to emit something, but the source is
 not meant to be formatted into a manual pages to begin with, and
 also its contents are a bit stale.  It may be a good first step in
 the right direction, but needs more work to at least get the
 mark-up right before public consumption.

 Will hold.

* jk/branch-at-publish-rebased (2014-01-17) 5 commits
 . t1507 (rev-parse-upstream): fix typo in test title
 . implement @{publish} shorthand
 . branch_get: provide per-branch pushremote pointers
 . branch_get: return early on error
 . sha1_name: refactor upstream_mark

 Give an easier access to the tracking branches from "other" side in
 a triangular workflow by introducing B@{publish} that works in a
 similar way to how B@{upstream} does.

 Meant to be used as a basis for whatever Ram wants to build on.

 Ejected from 'pu' to make room for fc/publish-vs-upstream topic.

* rb/merge-prepare-commit-msg-hook (2014-01-10) 4 commits
 - merge: drop unused arg from abort_commit method signature
 - merge: make prepare_to_commit responsible for write_merge_state
 - t7505: ensure cleanup after hook blocks merge
 - t7505: add missing &&

 Expose more merge states (e.g. $GIT_DIR/MERGE_MODE) to hooks that
 run during "git merge".  The log message stresses too much on one
 hook, prepare-commit-msg, but it would equally apply to other hooks
 like post-merge, I think.

 Waiting for a reroll.

* jl/submodule-recursive-checkout (2013-12-26) 5 commits
 - Teach checkout to recursively checkout submodules
 - submodule: teach unpack_trees() to update submodules
 - submodule: teach unpack_trees() to repopulate submodules

 - WIP: document what we want at the end
 - graph: remove unused code a bit
 - graph: stuff the current commit into graph->columns[]

 This was primarily a RFH ($gmane/239580).

 primarily for wider distribution of the preview edition.

 Needs to be rebased, now the pack-bitmap series is in.

* tg/perf-lib-test-perf-cleanup (2013-09-19) 2 commits
 - perf-lib: add test_perf_cleanup target
 - perf-lib: split starting the test from the execution

 Add test_perf_cleanup shell function to the perf suite, that allows
 the script writers to define a test with a clean-up action.

 Will hold.

 Move remote-hg and remote-bzr out of contrib/.  There were some

 I tend to agree with John Keeping that remote helpers that are
 actively maintained can and should aim to graduate from my tree and
 given to the user directly.

  (merged to 'next' on 2014-04-22 at 4f98483)
 + merge: enable defaulttoupstream by default

 + mergetool: document the default for --[no-]prompt
  (merged to 'next' on 2014-04-22 at dcaec94)
 + mergetool: run prompt only if guessed tool

 mergetool.prompt used to default to 'true', always causing a confirmation
 "do you really want to run the tool on this path" to be shown.

 Among the two purposes the prompt serves, ignore the use case to
 confirm that the user wants to view particular path with the named
 tool, and make the prompt only to confirm the choice of the tool
 made by autodetection and defaulting.  For those who configured the
 tool explicitly, the prompt shown for the latter purpose is simply

 Strictly speaking, this is a backward incompatible change and the
 users need to explicitly set the variable to 'true' if they want to
 resurrect the now-ignored use case.

 messages going back and forth but it does not appear that the
 design issues have been worked out among participants yet.

* ym/fix-opportunistic-index-update-race (2014-04-10) 2 commits
  (merged to 'next' on 2014-04-16 at cb92f4f)
 + read-cache.c: verify index file before we opportunistically update it
 + wrapper.c: add xpread() similar to xread()

 Read-only operations such as "git status" that internally refreshes
 the index write out the refreshed index to the disk to optimize
 future accesses to the working tree, but this could race with a
 "read-write" operation that modify the index while it is running.
 Detect such a race and avoid overwriting the index.

 Duy raised a good point that we may need to do the same for the
 normal writeout codepath, not just the "opportunistic" update
 codepath.  While that is true, nobody sane would be running two
 simultaneous operations that are clearly write-oriented competing
 with each other against the same index file.  So in that sense that
 can be done as a less urgent follow-up for this topic.

 Will keep in 'next' for the remainder of the cycle.

 Refactor and fix corner-case bugs in the lockfile API, all looked

 Expecting a reroll.

* mt/patch-id-stable (2014-05-06) 6 commits
 - test doc: test_write_lines does not split its arguments
  (merged to 'next' on 2014-05-02 at cfa251b)
 + default is now stable
 + patch-id: change default to stable
  (merged to 'next' on 2014-05-02 at b69326a)
 + patch-id-test: test stable and unstable behaviour
 + test: add test_write_lines helper
 + patch-id: make it stable against hunk reordering

 Introduce a new way to compute patch-id for a patch that is not
 affected by the order of the paths that appear in the input.

 Will merge to 'next' and keep it there for the remainder of the cycle.

* jc/apply-ignore-whitespace (2014-03-26) 1 commit
  (merged to 'next' on 2014-04-04 at 53779a7)
 + apply --ignore-space-change: lines with and without leading whitespaces do 
not match

 "--ignore-space-change" option of "git apply" ignored the
 spaces at the beginning of line too aggressively, which is
 inconsistent with the option of the same name "diff" and "git diff"

 Will keep in 'next' for the remainder of the cycle.

* as/grep-fullname-config (2014-03-20) 1 commit
  (merged to 'next' on 2014-03-28 at 810a076)
 + grep: add grep.fullName config variable

 Add a configuration variable to force --full-name to be default for
 "git grep".

 This may cause regressions on scripted users that do not expect
 this new behaviour.

 Will keep in 'next' for the remainder of the cycle.

 by making the borrowee and borrowers aware of each other.

 Will hold.

 + mingw: activate alloca
  (merged to 'next' on 2014-04-08 at 6b74773)
 + combine-diff: speed it up, by using multiparent diff tree-walker directly
 + tree-diff: rework diff_tree() to generate diffs for multiparent cases as well
 + Portable alloca for Git
  (merged to 'next' on 2014-03-31 at 16a7bd4)
 + tree-diff: reuse base str(buf) memory on sub-tree recursion
 + tree-diff: no need to call "full" diff_tree_sha1 from show_path()
 + tree-diff: rework diff_tree interface to be sha1 based
 + tree-diff: diff_tree() should now be static
 + tree-diff: remove special-case diff-emitting code for empty-tree cases
  (merged to 'next' on 2014-03-25 at cfcbdac)
 + tree-diff: simplify tree_entry_pathcmp
 + tree-diff: show_path prototype is not needed anymore
 + tree-diff: rename compare_tree_entry -> tree_entry_pathcmp
 + tree-diff: move all action-taking code out of compare_tree_entry()
 + tree-diff: don't assume compare_tree_entry() returns -1,0,1
  (merged to 'next' on 2014-03-21 at d872679)
 + tree-diff: consolidate code for emitting diffs and recursion in one place
 + tree-diff: show_tree() is not needed
 + tree-diff: no need to pass match to skip_uninteresting()
 + tree-diff: no need to manually verify that there is no mode change for a path
 + combine-diff: move changed-paths scanning logic into its own function
 + combine-diff: move show_log_first logic/action out of paths scanning

 Instead of running N pair-wise diff-trees when inspecting a
 N-parent merge, find the set of paths that were touched by walking
 N+1 trees in parallel.  These set of paths can then be turned into
 N pair-wise diff-tree results to be processed through rename
 detections and such.  And N=2 case nicely degenerates to the usual
 2-way diff-tree, which is very nice.

 Will keep in 'next' for the remainder of the cycle.

* jc/format-patch (2013-04-22) 2 commits
 . format-patch: --inline-single
 . format-patch: rename "no_inline" field

 A new option to send a single patch to the standard output to be
 appended at the bottom of a message.  I personally have no need for
 this, but it was easy enough to cobble together.  Tests, docs and
 stripping out more MIMEy stuff are left as exercises to interested
