f63ed085e2 Merge branch 'es/rebase-i-count-todo' into maint
"git rebase -i" recently started to include the number of
commits in the insn sheet to be processed, but on a platform
that prepends leading whitespaces to "wc -l" output, the numbers
are shown with extra whitespaces that aren't necessary.

28c8cfc363 rebase-interactive: suppress whitespace preceding item count
97f05f43 (Show number of TODO items for interactive rebase, 2014-12-10)
taught rebase-interactive to compute an item count with 'wc -l' and
display it in the instruction list comments:

    # Rebase 46640c6..5568fd5 onto 46640c6 (4 TODO item(s))

On Mac OS X, however, it renders as:

    # Rebase 46640c6..5568fd5 onto 46640c6 (       4 TODO item(s))

since 'wc -l' indents its output with leading spaces. Fix this.

edb72d5511 rebase -i: use full object name internally throughout the script
In earlier days, the abbreviated commit object name shown to the end
users were generated with hardcoded --abbrev=7; 56895038 (rebase
-i: respect core.abbrev, 2013-09-28) tried to make it honor the user
specified core.abbrev, but it missed the very initial invocation of
the editor.

These days, we try to use the full 40-hex object names internally to
avoid ambiguity that can arise after rebase starts running.  Newly
created objects during the rebase may share the same prefix with
existing commits listed in the insn sheet.  These object names are
shortened just before invoking the sequence editor to present the
insn sheet to the end user, and then expanded back to full object
names when the editor returns.

But the code still used the shortened names when preparing the insn
sheet for the very first time, resulting "7 hexdigits or more"
output to the user.  Change the code to use full 40-hex commit
object names from the very beginning to make things more uniform.

512477b175 tests: use "env" to run commands with temporary env-var settings
Ordinarily, we would say "VAR=VAL command" to execute a tested
command with environment variable(s) set only for that command.
This however does not work if 'command' is a shell function (most
notably 'test_must_fail'); the result of the assignment is retained
and affects later commands.

To avoid this, we used to assign and export environment variables
and run such a test in a subshell, like so:

        (
                VAR=VAL && export VAR &&
                test_must_fail git command to be tested
        )

But with "env" utility, we should be able to say:

        test_must_fail env VAR=VAL git command to be tested

which is much shorter and easier to read.

75c6976655 rebase -i: fix short SHA-1 collision
The 'todo' sheet for interactive rebase shows abbreviated SHA-1's and
then performs its operations upon those shortened values. This can lead
to an abort if the SHA-1 of a reworded or edited commit is no longer
unique within the abbreviated SHA-1 space and a subsequent SHA-1 in the
todo list has the same abbreviated value.

For example:

  edit f00dfad first
  pick badbeef second

If, after editing, the new SHA-1 of "first" also has prefix badbeef,
then the subsequent 'pick badbeef second' will fail since badbeef is no
longer a unique SHA-1 abbreviation:

  error: short SHA1 badbeef is ambiguous.
  fatal: Needed a single revision
  Invalid commit name: badbeef

Fix this problem by expanding the SHA-1's in the todo list before
performing the operations.

31cd827525 t3404: make tests more self-contained
As its very first action, t3404 installs (via set_fake_editor) a
specialized $EDITOR which simplifies automated 'rebase -i' testing. Many
tests rely upon this setting, thus tests which need a different editor
must take extra care upon completion to restore $EDITOR in order to
avoid breaking following tests. This places extra burden upon such tests
and requires that they undesirably have extra knowledge about
surrounding tests. Ease this burden by having each test install the
$EDITOR it requires, rather than relying upon a global setting.

89b0230a20 die_with_status: use "printf '%s\n'", not "echo"
Some implementations of 'echo' (e.g. dash's built-in) interpret
backslash sequences in their arguments.

This triggered at least one bug: the error message of "rebase -i" was
turning \t in commit messages into actual tabulations. There may be
others.

Using "printf '%s\n'" instead avoids this bad behavior, and is the form
used by the "say" function.

26cd160cb1 rebase -i: use a better reflog message
Now that the "checkout" invoked internally from "rebase -i" knows to
honor GIT_REFLOG_ACTION, we can start to use it to write a better
reflog message when "rebase anotherbranch", "rebase --onto branch",
etc. internally checks out the new fork point.  We will write:

  rebase -i: checkout master

instead of the old

  rebase -i

As all the calls git-rebase--interactive make to underlying git
commands that leave reflog messages are preceded by the internal
comment_for_reflog helper function, which uses the original value of
the GIT_REFLOG_ACTION variable it saw when it first started, the new
assignments to GIT_REFLOG_ACTION actively contaminate the value of
the variable, knowing that it will be reset to a sane value before
it is used again.  This does not generally hold true but it should
suffice for now.

ecfe1ea96f rebase -i: fix misleading error message after 'exec no-such' instruction
When the todo sheet of interactive rebase instructs to run a non-existing
command, the operation stops with the following error:

  Execution failed: no-such
  You can fix the problem, and then run

          git rebase --continue

  fatal: 'rebase' appears to be a git command, but we were not
  able to execute it. Maybe git-rebase is broken?

The reason is that the shell that attempted to run the command exits with
code 127. rebase--interactive just forwards this code to the caller (the
git wrapper). But our smart run-command infrastructure detects this
special exit code and turns it into ENOENT, which in turn is interpreted
by the git wrapper as if the external command that it just executed did
not exist. This is finally translated to the misleading last two lines in
error message cited above.

Fix it by translating the error code before it is forwarded.

c214538416 rebase -i: teach "--exec <cmd>"
During an interactive rebase session, it is sometimes desirable to
run tests on each commit in the resulting history.  This can be done
by adding "exec <test command>" when editing the insn sheet, but the
command used for testing is often the same for all resulting commits.

By passing "--exec <cmd>" from the command line, automatically add
these "exec" lines after each commit in the final history.  To work
well with the --autosquash option, these are added at the end of
each run of "fixup" and "squash".

dc801e71a7 diff --stat: use less columns for change counts
Number of columns required for change counts is now computed based on
the maximum number of changed lines instead of being fixed. This means
that usually a few more columns will be available for the filenames
and the graph.

The graph width logic is also modified to include enough space for
"Bin XXX -> YYY bytes".

If changes to binary files are mixed with changes to text files,
change counts are padded to take at least three columns. And the other
way around, if change counts require more than three columns, then
"Bin"s are padded to align with the change count. This way, the +-
part starts in the same column as "XXX -> YYY" part for binary files.
This makes the graph easier to parse visually thanks to the empty
column. This mimics the layout of diff --stat before this change.

Tests and the tutorial are updated to reflect the new --stat output.
This means either the removal of extra padding and/or the addition of
up to three extra characters to truncated filenames. One test is added
to check the graph alignment when a binary file change and text file
change of more than 999 lines are committed together.

a6754cda43 rebase -i continue: don't skip commits that only change submodules
When git-rebase--interactive stops due to a conflict and the only change
to be committed is in a submodule, the test for whether there is
anything to be committed ignores the staged submodule change.  This
leads rebase to skip creating the commit for the change.

While unstaged submodule changes should be ignored to avoid needing to
update submodules during a rebase, it is safe to remove the
--ignore-submodules option to diff-index because --cached ensures that
it is only checking the index.  This was discussed in [1] and a test is
included to ensure that unstaged changes are still ignored correctly.

the user, if changes are added to the index, "rebase --continue" fails
with this message, which may technically be correct, but does not point
at the real problem:

.../git-rebase--interactive: line 774: .../.git/rebase-merge/author-script: No such file or directory

We could try auto-amending HEAD, but this goes against the logic of
.git/rebase-merge/author-script (see also the testcase 'auto-amend only
edited commits after "edit"' in t3404-rebase-interactive.sh) to
auto-amend something the user hasn't explicitely asked to edit.

Instead of doing anything automatically, detect the situation and give a
clean error message. While we're there, also clarify the error message in
case '. "$author_script"' fails, which now corresponds to really weird
senario where the author script exists but can't be read.

12bf828348 rebase -i -p: include non-first-parent commits in todo list
Consider this graph:

        D---E    (topic, HEAD)
       /   /
  A---B---C      (master)
   \
    F            (topic2)

and the following three commands:
  1. git rebase -i -p A
  2. git rebase -i -p --onto F A
  3. git rebase -i -p B

Currently, (1) and (2) will pick B, D, C, and E onto A and F,
respectively.  However, (3) will only pick D and E onto B, but not C,
which is inconsistent with (1) and (2).  As a result, we cannot modify C
during the interactive-rebase.

The current behavior also creates a bug if we do:
  4. git rebase -i -p C

In (4), E is never picked.  And since interactive-rebase resets "HEAD"
to "onto" before picking any commits, D and E are lost after the
interactive-rebase.

This patch fixes the inconsistency and bug by ensuring that all children
of upstream are always picked.  This essentially reverts the commit:
  d80d6bc146

When compiling the todo list, commits reachable from "upstream" should
never be skipped under any conditions.  Otherwise, we lose the ability
to modify them like (3), and create a bug like (4).

Two of the tests contain a scenario like (3).  Since the new behavior
added more commits for picking, these tests need to be updated to
account for the additional pick lines.  A new test has also been added
for (4).

53f2ffa80c rebase: write a reflog entry when finishing
When we finish a rebase, our detached HEAD is at the final
result. We update the original branch ref with this result,
and then point the HEAD symbolic ref at the updated branch.
We write a reflog for the branch update, but not for the
update of HEAD.

Because we're already at the final result on the detached
HEAD, moving to the branch actually doesn't change our
commit sha1 at all. So in that sense, a reflog entry would
be pointless.

However, humans do read reflogs, and an entry saying "rebase
finished: returning to refs/heads/master" can be helpful in
understanding what is going on.

5cd3e10737 Fix false positives in t3404 due to SHELL=/bin/false
If the user's shell in NSS passwd is /bin/false (eg as found during Gentoo's
package building), the git-rebase exec tests will fail, because they call
$SHELL around the command, and in the existing testcase, $SHELL was not being
cleared sufficently.

This lead to false positive failures of t3404 on systems where the package
build user was locked down as noted above.

d4990c4b2f notes.c: Use two newlines (instead of one) when concatenating notes
When using combine_notes_concatenate() to concatenate notes, it currently
ensures exactly one newline character between the given notes. However,
when using builtin/notes.c:create_note() to concatenate notes (e.g. by
'git notes append'), it adds a newline character to the trailing newline
of the preceding notes object, thus resulting in _two_ newlines (aka. a
blank line) separating contents of the two notes.

This patch brings combine_notes_concatenate() into consistency with
builtin/notes.c:create_note(), by ensuring exactly _two_ newline characters
between concatenated notes.

The patch also changes a few notes-related selftests accordingly.

5c947e2c38 t3404 (rebase -i): introduce helper to check position of HEAD
The same code to check the position of HEAD is used by several
tests in this script.  Factor it out as a function and simplify it.

Noticed using an &&-chaining tester, because the current code
does not propagate the precise exit status from errors.

More importantly, avoiding these loops makes the test a little
simpler to read and decreases the vertical screen footprint of
