Jeff King 4ac5356c62 rebase: give a better error message for bogus branch
When you give a non-existent branch to git-rebase, it spits
out the usage. This can be confusing, since you may
understand the usage just fine, but simply have made a
mistake in the branch name.

Before:

  $ git rebase origin bogus
  Usage: git rebase ...

After:

  $ git rebase origin bogus
  fatal: no such branch: bogus
  Usage: git rebase ...

Jeff King 3b21a438c9 rebase: use explicit "--" with checkout
In the case of a ref/pathname conflict, checkout will
already do the right thing and checkout the ref. However,
for a non-existant ref, this has two advantages:

  1. If a file with that pathname exists, rebase will
     refresh the file from the index and then rebase the
     current branch instead of producing an error.

  2. If no such file exists, the error message using an
     explicit "--" is better:

       # before
       $ git rebase -i origin bogus
       error: pathspec 'bogus' did not match any file(s) known to git.
       Could not checkout bogus

       # after
       $ git rebase -i origin bogus
       fatal: invalid reference: bogus
       Could not checkout bogus

The problems seem to be trigger-able only through "git
rebase -i", as regular git-rebase checks the validity of the
branch parameter as a ref very early on. However, it doesn't
hurt to be defensive.

Martin von Zweigbergk 9474a029d5 rebase: only show stat if configured to true
If rebase.stat is set to true, a diffstat should be displayed. If it is
not set, it should default to false. However, if it is explicitly set to
false (or other value), a diffstat is still displayed, which is probably
not what most users would expect. Show diffstat only if it is set
to true.

Ramkumar Ramachandra 92c62a3f4f Porcelain scripts: Rewrite cryptic "needs update" error message
Although Git interally has the facility to differentiate between
porcelain and plubmbing commands and appropriately print errors,
several shell scripts invoke plubming commands triggering cryptic
plumbing errors to be displayed on a porcelain interface. This patch
replaces the "needs update" message in git-pull and git-rebase, when
`git update-index` is run, with a more friendly message.

Mike Lundy 93ce190cd1 rebase: support -X to pass through strategy options
git-rebase calls out to merge strategies, but did not support merge
strategy options so far.  Add this, in the same style used in
git-merge.

Sadly we have to do the full quoting/eval dance here, since
merge-recursive supports the --subtree=<path> option which potentially
contains whitespace.

This patch does not cover git rebase -i, which does not call any merge
strategy directly except in --preserve-merges, and even then only for
merges.

David D. Kilzer 25e9325040 Fix git rebase --continue to work with touched files
When performing a non-interactive rebase, sometimes
"git rebase --continue" will fail if an unmodified file is
touched in the working directory:

    You must edit all merge conflicts and then
    mark them as resolved using git add

This is caused by "git diff-files" reporting a difference
between the index and the filesystem:

    :100644 100644 d00491...... 000000...... M	file

The fix is to run "git update-index --refresh" before
"git diff-files" as is done in git-rebase--interactive.

Junio C Hamano 840b3ca758 rebase: protect against diff.renames configuration
We currently do not disable diff.renames configuration while rebase
internally runs "format-patch" to feed "am -3".

The end user configuration for "diff" should not affect the result
produced by the higher level command that is related to "diff" only
because internally it is implemented in terms of it.

For that matter, I have a feeling that format-patch should not even look
at diff.renames, but we seem to have been doing this for a long time so
there is no easy way to fix this thinko.

In any case, here is a much straightforward fix for "rebase".

Marc Branchaud b499549401 Teach rebase the --no-ff option.
For git-rebase.sh, --no-ff is a synonym for --force-rebase.

For git-rebase--interactive.sh, --no-ff cherry-picks all the commits in
the rebased branch, instead of fast-forwarding over any unchanged commits.

--no-ff offers an alternative way to deal with reverted merges.  Instead of
"reverting the revert" you can use "rebase --no-ff" to recreate the branch
with entirely new commits (they're new because at the very least the
committer time is different).  This obviates the need to revert the
reversion, as you can re-merge the new topic branch directly.  Added an
addendum to revert-a-faulty-merge.txt describing the situation and how to
use --no-ff to handle it.

Thomas Rast 96e19488f1 rebase: invoke post-rewrite hook
We have to deal with two separate code paths: a normal rebase, which
actually goes through git-am; and rebase {-m|-s}.

The only small issue with both is that they need to remember the
original sha1 across a possible conflict resolution.  rebase -m
already puts this information in $dotest/current, and we just
introduce a similar file for git-am.

Note that in git-am, the hook really only runs when coming from
git-rebase: the code path that sets the $dotest/original-commit file
is guarded by a test for $dotest/rebasing.

Junio C Hamano e1622bfcba Protect scripted Porcelains from GREP_OPTIONS insanity
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.

Junio C Hamano 61dfa1bb67 "rebase --onto A...B" replays history on the merge base between A and B
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').

The quiet option is maintained when git-am or git-rebase fails to apply
a patch. This means subsequent --resolved, --continue, --skip, --abort
invocations will be quiet if the original invocation was quiet.

Drop a handful of >&2 redirection; the rest of the program sends all the
