make a commit.

  - "git clean" honors a new configuration, "clean.requireforce".  When
    set to true, this makes "git clean" a no-op, preventing you
    from losing files by typing "git clean" when you meant to
    say "make clean".  You can still say "git clean -f" to
    override this.

  - "git log" family of commands learned --date={local,relative,default}
    option.  --date=relative is synonym to the --relative-date.
    --date=local gives the timestamp in local timezone.

* Updated behavior of existing commands.

  - When $GIT_COMMITTER_EMAIL or $GIT_AUTHOR_EMAIL is not set
    but $EMAIL is set, the latter is used as a substitute.

  - "git diff --stat" shows size of preimage and postimage blobs
    for binary contents.  Earlier it only said "Bin".

  - "git lost-found" shows stuff that are unreachable except
    from reflogs.

  - "git checkout branch^0" now detaches HEAD at the tip commit
    on the named branch, instead of just switching to the
    branch (use "git checkout branch" to switch to the branch,
    as before).

  - "git bisect next" can be used after giving only a bad commit
    without giving a good one (this starts bisection half-way to
    the root commit).  We used to refuse to operate without a
    good and a bad commit.

  - "git push", when pushing into more than one repository, does
    not stop at the first error.

  - "git archive" does not insist you to give --format parameter
    anymore; it defaults to "tar".

  - "git cvsserver" can use backends other than sqlite.

  - "gitview" (in contrib/ section) learned to better support
    "git-annotate".

  - "git diff $commit1:$path2 $commit2:$path2" can now report
    mode changes between the two blobs.

  - Local "git fetch" from a repository whose object store is
    one of the alternates (e.g. fetching from the origin in a
    repository created with "git clone -l -s") avoids
    downloading objects unnecessarily.

  - "git blame" uses .mailmap to canonicalize the author name
    just like "git shortlog" does.

  - "git pack-objects" pays attention to pack.depth
    configuration variable.

  - "git cherry-pick" and "git revert" does not use .msg file in
    the working tree to prepare commit message; instead it uses
    $GIT_DIR/MERGE_MSG as other commands do.
