"git pack-objects" learned another algorithm to compute the set of
objects to send, that trades the resulting packfile off to save
traversal cost to favor small pushes.
* ds/push-sparse-tree-walk:
pack-objects: create GIT_TEST_PACK_SPARSE
pack-objects: create pack.useSparse setting
revision: implement sparse algorithm
list-objects: consume sparse tree walk
revision: add mark_tree_uninteresting_sparse

The test lint learned to catch non-portable "sed" options.
* tb/test-lint-sed-options:
test-lint: only use only sed [-n] [-e command] [-f command_file]

A new date format "--date=human" that morphs its output depending
on how far the time is from the current time has been introduced.
"--date=auto" can be used to use this new format when the output is
going to the pager or to the terminal and otherwise the default
format.
* lt/date-human:
Add `human` date format tests.
Add `human` format to test-tool
Add 'human' date format documentation
Replace the proposed 'auto' mode with 'auto:'
Add 'human' date format

Instead of going through "git-rebase--am" scriptlet to use the "am"
backend, the built-in version of "git rebase" learned to drive the
"am" backend directly.
* js/rebase-am:
built-in rebase: call `git am` directly
rebase: teach `reset_head()` to optionally skip the worktree
rebase: avoid double reflog entry when switching branches
rebase: move `reset_head()` into a better spot

A new encoding UTF-16LE-BOM has been invented to force encoding to

The commit-graph facility did not work when in-core objects that
are promoted from unknown type to commit (e.g. a commit that is
accessed via a tag that refers to it) were involved, which has been

"git checkout -b <new> [HEAD]" to create a new branch from the
current commit and check it out ought to be a no-op in the index
and the working tree in normal cases, but there are corner cases
that do require updates to the index and the working tree. Running
it immediately after "git clone --no-checkout" is one of these
cases that an earlier optimization kicked in incorrectly, which has
been fixed.

Users who want UTF-16 files in the working tree set the .gitattributes
like this:
test.txt working-tree-encoding=UTF-16
The unicode standard itself defines 3 allowed ways how to encode UTF-16.
The following 3 versions convert all back to 'g' 'i' 't' in UTF-8:
a) UTF-16, without BOM, big endian:
$ printf "\000g\000i\000t" | iconv -f UTF-16 -t UTF-8 | od -c
0000000 g i t
b) UTF-16, with BOM, little endian:
$ printf "\377\376g\000i\000t\000" | iconv -f UTF-16 -t UTF-8 | od -c
0000000 g i t
c) UTF-16, with BOM, big endian:
$ printf "\376\377\000g\000i\000t" | iconv -f UTF-16 -t UTF-8 | od -c
0000000 g i t
Git uses libiconv to convert from UTF-8 in the index into ITF-16 in the
working tree.
After a checkout, the resulting file has a BOM and is encoded in "UTF-16",
in the version (c) above.
This is what iconv generates, more details follow below.
iconv (and libiconv) can generate UTF-16, UTF-16LE or UTF-16BE:
d) UTF-16
$ printf 'git' | iconv -f UTF-8 -t UTF-16 | od -c
0000000 376 377 \0 g \0 i \0 t
e) UTF-16LE
$ printf 'git' | iconv -f UTF-8 -t UTF-16LE | od -c
0000000 g \0 i \0 t \0
f) UTF-16BE
$ printf 'git' | iconv -f UTF-8 -t UTF-16BE | od -c
0000000 \0 g \0 i \0 t
There is no way to generate version (b) from above in a Git working tree,
but that is what some applications need.
(All fully unicode aware applications should be able to read all 3 variants,
but in practise we are not there yet).
When producing UTF-16 as an output, iconv generates the big endian version
with a BOM. (big endian is probably chosen for historical reasons).
iconv can produce UTF-16 files with little endianess by using "UTF-16LE"
as encoding, and that file does not have a BOM.
Not all users (especially under Windows) are happy with this.
Some tools are not fully unicode aware and can only handle version (b).
Today there is no way to produce version (b) with iconv (or libiconv).
Looking into the history of iconv, it seems as if version (c) will
be used in all future iconv versions (for compatibility reasons).
Solve this dilemma and introduce a Git-specific "UTF-16LE-BOM".
libiconv can not handle the encoding, so Git pick it up, handles the BOM
and uses libiconv to convert the rest of the stream.
(UTF-16BE-BOM is added for consistency)
