"git describe" takes a commit and gives it a name based on tags in
its neighbourhood. The command does take a commit-ish but when
given a tag that points at a commit, it should dereference the tag
before computing the name for the commit.
As the whole processing is internally delegated to name-rev, if we
unwrap tags down to the underlying commit when invoking name-rev, it
will make the name-rev issue an error message based on the unwrapped
object name (i.e. either 40-hex object name, or "$tag^0") that is
different from what the end-user gave to the command when the commit
cannot be described. Introduce an internal option --peel-tag to the
name-rev to tell it to unwrap a tag in its input from the command
line.

"git name-rev --stdin" has been fixed to convert an object name that
points at a tag to a refname of the tag. The codepath to handle its
command line arguments, however, fed the commit that the tag points
at to the underlying naming machinery.
With this fix, you will get this:
$ git name-rev --refs=tags/\* --name-only $(git rev-parse v1.8.3 v1.8.3^0)
v1.8.3
v1.8.3^0
which is the same as what you would get from the fixed "--stdin" variant:
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --refs=tags/\* --name-only
v1.8.3
v1.8.3^0

"git name-rev" is supposed to convert given object names into
strings that name the same objects based on refs, that can be fed to
"git rev-parse" to get the same object names back, so the output for
the commit object v1.8.3^0 (i.e. the commit tagged as v1.8.3)
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --stdin
8af06057d0c31a24e8737ae846ac2e116e8bafb9
edca415256 (tags/v1.8.3^0)
has to have "^0" at the end, as "edca41" is a commit, not the tag
that references it. But we do not get anything for the tag object
(8af0605) itself.
This is because the command however did not bother to see if the
object is at the tip of some ref, and failed to convert a tag
object.
Teach it to show this instead:
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --stdin
8af06057d0c31a24e8737ae846ac2e116e8bafb9 (tags/v1.8.3)

When an user wants to filter specific ref using the --refs option,
the pattern needs to match the full ref, e.g. --refs=refs/tags/v1.*.
It'd be convenient to specify a subpath of ref pattern. For
example, --refs=origin/* can find refs/remotes/origin/master by
searching the pattern against its substrings in turn:
refs/remotes/origin/master
remotes/origin/master
origin/master
If it finds a match in a subpath, unambigous part of the ref path will
be removed in the output.

remote_find_tracking() populates the query struct with an allocated
string in the dst member. So, we do not need to xstrdup() the string,
since we can transfer ownership from the query struct (which will go
out of scope at the end of this function) to our callback struct, but
we must free the string if it will not be used so we will not leak

The compiler can short-circuit the evaluation of conditions strung

This is a pure code movement of the machinery for copying notes to
rewritten objects. This code was located in builtin/notes.c for
historical reasons. In order to make it available to builtin/commit.c
it was declared in builtin.h. This was more of an accident of history
than a concious design, and we now want to make this machinery more
widely available.
Hence, this patch moves the code into the new notes-utils.[hc] files
which are included into libgit.a. Except for adjusting #includes
accordingly, this patch merely moves the relevant functions verbatim
into the new files.

Most users seem to like having colors enabled, and colors can help
beginners to understand the output of some commands (e.g. notice
immediately the boundary between commits in the output of "git log").
Many tutorials tell the users to set color.ui=auto as a very first step,
which tend to indicate that color.ui=none is not the recommanded value,
hence should not be the default.
These tutorials would benefit from skipping this step and starting the
real Git manipulations earlier. Other beginners do not know about
color.ui=auto, and may not discover it by themselves, hence live with
black&white outputs while they may have preferred colors.
A few people (e.g. color-blind) prefer having no colors, but they can
easily set color.ui=never for this (and googling "disable colors in git"
already tells them how to do so), but this needs not occupy space in
beginner-oriented documentations.
A transition period with Git emitting a warning when color.ui is unset
would be possible, but the discomfort of having the warning seems
superior to the benefit: users may be surprised by the change, but not
harmed by it.
The default value is changed, and the documentation is reworded to
mention "color.ui=false" first, since the primary use of color.ui after
this change is to disable colors, not to enable it.

With this change, the output of the push (with push.default set to
current) changes subtly from:
$ git push
...
* [new branch] HEAD -> push-current-head
to:
$ git push
...
* [new branch] push-current-head -> push-current-head
This patch was written with a different motivation. There is a problem
unique to push.default = current:
# on branch push-current-head
$ git push
# on another terminal
$ git checkout master
# return to the first terminal
# the push tried to push master!
This happens because the 'git checkout' on the second terminal races
with the 'git push' on the first terminal. Although this patch does not
solve the core problem (there is still no guarantee that 'git push' on
the first terminal will resolve HEAD before 'git checkout' changes HEAD
on the second), it works in practice.

Setting push.default to current adds the refspec "HEAD" for the
transport layer to handle. If "HEAD" doesn't resolve to a branch (and
since no refspec rhs is specified), the push fails after some time with
a cryptic error message:
$ git push
error: unable to push to unqualified destination: HEAD
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to 'git@github.com:artagnon/git'
Fail early with a nicer error message:
$ git push
fatal: You are not currently on a branch.

state now, use
