The previous patch didn't parse "rebase --onto A...B" correctly when A
isn't an empty string. It also tried to be careful to notice a case in
which there are more than one merge bases, but forgot to give --all option
to merge-base, making the test pointless.
Fix these problems and add a test script to verify. Improvements to the
script to parse A...B syntax was taken from review comments by Johannes
Schindelin.

If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect. For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.
The approach taken by this change to address this issue is to protect only
our own use of grep/egrep. Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.
On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

This is in spirit similar to "checkout A...B". To re-queue a new set of
patches for a series that the original author prepared to apply on 'next'
on the same base as before, you would do something like this:
$ git checkout next^0
$ git am -s rerolled-series.mbox
$ git rebase --onto next...jh/notes next
The first two commands recreates commits to be rebased as the original
author intended (i.e. applies directly on top of 'next'), and the rebase
command replays that history on top of the same commit the series being
replaced was built on (which is typically much older than the tip of
'next').

git-am and git-rebase are talkative scripts. Teach them to be quiet when
told, allowing them to speak only when they fail or experience errors.
The quiet option is maintained when git-am or git-rebase fails to apply

invocations will be quiet if the original invocation was quiet.

Teach git-rebase a new option --root, which instructs it to rebase the
entire history leading up to <branch>. This option must be used with
--onto <newbase>, and causes commits that already exist in <newbase>
to be skipped. (Normal operation skips commits that already exist in
<upstream> instead.)
One possible use-case is with git-svn: suppose you start hacking
(perhaps offline) on a new project, but later notice you want to
commit this work to SVN. You will have to rebase the entire history,
including the root commit, on a (possibly empty) commit coming from
git-svn, to establish a history connection. This previously had to
be done by cherry-picking the root commit manually.

If you have unstaged changes in your working tree and try to
rebase, you will get the cryptic "foo: needs update"
message, but nothing else. If you have staged changes, you
get "your index is not up-to-date".
Let's improve this situation in two ways:
- for unstaged changes, let's also tell them we are
canceling the rebase, and why (in addition to the "needs
update" lines)
- for the staged changes case, let's use language that is a
little more clear to the user: their index contains
uncommitted changes

As a result of implementation details, 'git rebase' could
previously only preserve merges in interactive mode. That
limitation was hard for users to understand and awkward to
explain.
This patch works around it by running the interactive rebase
helper git-rebase--interactive with GIT_EDITOR set to ':'
when the user passes "-p" but not "-i" to the rebase command.
The effect is that the interactive rebase helper is used but
the user never sees an editor.

"merge" and "reset" leave the original point in history in ORIG_HEAD,
which makes it easy to go back to where you were before you inflict a
major damage to your history and realize that you do not like the result
at all. These days with reflog, we technically do not need to use
ORIG_HEAD, but it is a handy way nevertheless.
This teaches "am" and "rebase" (all forms --- the vanilla one that uses
"am" as its backend, "-m" variant that cherry-picks, and "--interactive")
to do the same.
The original idea and a partial implementation to do this only for "rebase
-m" was by Brian Gernhardt; this extends on his idea.

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

A lot of shell scripts contained stuff starting with
while case "$#" in 0) break ;; esac
and similar. I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance. It
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
scripts, anyway, the added readability should be worth the change.
