This teaches "git rebase [--onto O] A B" to omit an unnecessary checkout
of branch B before it goes on.
"git-rebase" originally was about rebasing the current branch to somewhere
else, and when the extra parameter to name which branch to rebase was
added, it defined the semantics to the safest but stupid "first switch to
the named branch and then operate exactly the same way as if we were
already on that branch".
But the first thing the real part of "rebase" does is to reset the work
tree and the index to the "onto" commit. Which means the "rebase that
branch" form switched the work tree to the tip of the branch only to
immediately switch again to another commit. This was wasteful.

When rebasing changes that contain issues that the pre-commit hook flags
as problematic, the rebase cannot be continued. However, rebase is about
transplanting commits that are already made with as little distortion as
possible, and pre-commit check should not interfere.
Earlier, c5b09fe (Avoid update hook during git-rebase --interactive,
2007-12-19) fixed "rebase -i", but "rebase -m" shared the same issue.

The new option --rebasing is used internally for rebase to tell am that
it is being used for its purpose. This would leave .dotest/rebasing to
help "completion" scripts tell if the ongoing operation is am or rebase.
Also the option at the same time stands for --binary, -3 and -k which
are always given when rebase drives am as its backend.
Using the information "am" leaves, git-completion.bash tells ongoing
rebase and am apart.

When you have a file called HEAD in your work tree, many commands that
our scripts feed "HEAD" to would complain about the rev vs path
ambiguity. A solution is to form command line more carefully by
appending -- to them, which makes it clear that we mean HEAD rev not
HEAD file.

happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant. In most cases, this has been
replaced by a straight condition using "test". "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin. Since none of them is likely to run the git

When a topic branch is rebased, some of whose commits are already
cherry-picked upstream:
o--X--A--B--Y <- master
\

then 'git rebase -m master' would report:

Earlier, "git rerere" was enabled by creating the directory
.git/rr-cache. That is definitely not in line with most other
features, which are enabled by a config variable.
So, check the config variable "rerere.enabled". If it is set
to "false" explicitely, do not activate rerere, even if
.git/rr-cache exists. This should help when you want to disable
rerere temporarily.
If "rerere.enabled" is not set at all, fall back to detection
of the directory .git/rr-cache.

Consider this history:
o--o-...-B <- origin
\ \
x--x--M--x--x <- master
In this situation, rebase considers master fully up-to-date and would
not do anything. However, if there were additional commits on origin,
the rebase would run and move the commits x on top of origin.
Here we change rebase to short-circuit out only if the history since origin
is strictly linear. Consequently, the above as well as a history like this
would be linearized:
o--o <- origin
\
x--x
\ \
x--M--x--x <- master

Don't you just hate the fact sometimes, that git-rebase just applies
the patches, without any possibility to edit them, or rearrange them?
With "--interactive", git-rebase now lets you edit the list of patches,
so that you can reorder, edit and delete patches.
Such a list will typically look like this:
pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...
By replacing the command "pick" with the command "edit", you can amend
that patch and/or its commit message, and by replacing it with "squash"
you can tell rebase to fold that patch into the patch before that.
It is derived from the script sent to the list in

When you want to amend the commit message of 3 commits before
the tip of the current branch, say 'master',
A--B--C--D--E(master)
it is sometimes handy to make your head detached at that commit
with:
$ git checkout HEAD~3 ;# check out B
$ git commit --amend ;# without modifying contents...
to create:
.B'(HEAD)
/
A--B--C--D--E(master)
and then rebase 'master' branch onto HEAD with this:
$ git rebase HEAD master
to result in:
.B'-C'-D'-E(master=HEAD)
/
A--B--C--D--E
However, the current code interprets HEAD after it switches to
the branch 'master', which means the rebase will not do
anything. You have to say something unwieldly like this
instead:
$ git rebase $(git rev-parse HEAD) master
This fixes it by expanding the $onto commit name before
switching to the target branch.

If a three-way merge in git-rebase generates a conflict then we
should take advantage of git-merge-recursive's ability to include
the branch name of each side of the conflict hunk by setting the
GITHEAD_* environment variables.
In the case of rebase there aren't really two clear branches; we
have the branch we are rebasing onto, and we have the branch we are
currently rebasing. Since most conflicts will be arising between
the user's current branch and the branch they are rebasing onto
we assume the stuff that isn't in the current commit is the "onto"
branch and the stuff in the current commit is the "current" branch.
This assumption may however come up wrong if the user resolves one
conflict in such a way that it conflicts again on a future commit
also being rebased. In this case the user's prior resolution will
appear to be in the "onto" part of the hunk.

Junio rightly pointed out that the --reflog-action parameter
was starting to get out of control, as most porcelain code
needed to hand it to other porcelain and plumbing alike to
ensure the reflog contained the top-level user action and
not the lower-level actions it invoked.
At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION
environment variable.
