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

We would need to start slowing down to prepare for -rc0 preview at
the end of this week and then feature freeze.  Some topics that
joined 'next' late may want to stay there for the remainder of this
cycle.  Many of the accumulated fixes have been flushed to 'maint'
and Git 2.0.2 has been tagged.

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

    http://git-blame.blogspot.com/p/git-public-repositories.html

 (this branch is used by jc/reopen-lock-file.)

 An experiment to use two files (the base file and incremental

 changes.

 - git-rebase: print name of rev when using shorthand

 Teach "git rebase -" to report the concrete name of the branch
 (i.e. the previous one).

 But it stops short and does not do the same for "git rebase @{-1}".
 Expecting a reroll.


* tr/merge-recursive-index-only (2014-02-05) 3 commits
 - merge-recursive: -Xindex-only to leave worktree unchanged
 - merge-recursive: internal flag to avoid touching the worktree
 - merge-recursive: remove dead conditional in update_stages()

 . merge-recursive: allow storing conflict hunks in index
 . revision: fold all merge diff variants into an enum merge_diff_mode

 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.

 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.

 - merge: drop unused arg from abort_commit method signature

 - 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.


* jc/graph-post-root-gap (2013-12-30) 3 commits
 - 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).

 - show-branch.c: update comment style

 Waiting for the final step to lift the hard-limit before sending it out.


* jh/submodule-tests (2014-04-17) 1 commit
 - t7410: 210 tests for various 'git submodule update' scenarios

 More or less abandoned.  Will drop.

--------------------------------------------------
[Cooking]

* jc/reopen-lock-file (2014-07-14) 1 commit

* jc/test-lazy-prereq (2014-06-13) 1 commit
 - tests: drop GIT_*_TIMING_TESTS environment variable support

 Test-script clean-up.

 Will hold.


* mt/patch-id-stable (2014-06-10) 1 commit
 - patch-id: change default to stable

 Teaches "git patch-id" to compute the patch ID that does not change
 when the files in a single patch is reordered. As this new algorithm
 is backward incompatible, the last bit to flip it to be the default
 is left out of 'master' for now.

 Will hold.
