i18n: add stub Q_() wrapper for ngettext

The Q_ function translates a string representing some pharse with an
alternative plural form and uses the 'count' argument to choose which
form to return.  Use of Q_ solves the "%d noun(s)" problem in a way
that is portable to languages outside the Germanic and Romance
families.

In English, the semantics of Q_(sing, plur, count) are roughly
equivalent to

count == 1 ? _(sing) : _(plur)

while in other languages there can be more variants (count == 0; more
random-looking rules based on the historical pronunciation of the
number).  Behind the scenes, the singular form is used to look up a
family of translations and the plural form is ignored unless no
translation is available.

Define such a Q_ in gettext.h with the English semantics so C code can
start using it to mark phrases with a count for translation.

The name "Q_" is taken from subversion and stands for "quantity".
Many projects just use ngettext directly without a wrapper analogous
to _; we should not do so because git's gettext.h is meant not to
conflict with system headers that might include libintl.h.

prerequisite. Newly failing tests that do not depend on output from
Porcelain would be bugs due to messages that should not have been
marked for translation.

Note that the string we're using ("# GETTEXT POISON #") intentionally
starts the pound sign. Some of Git's tests such as
t3404-rebase-interactive.sh rely on interactive editing with a fake

array of structs, to be assigned with *(dst) = *(src)) will need some
other compatibility macro, though.

Luckily, as the glibc manual hints, such systems tend to provide the
__va_copy macro (introduced in GCC in March, 1997).  By using that if
it is available, we can cover our bases pretty well.

  ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
     AC_RUN_IFELSE now warn if the first argument failed to use

     a compelling reason why you cannot use AC_LANG_SOURCE but must
     avoid the warning.

The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM}
take care to supply the previously computed set of #defines (and
include standard headers if so desired) for preprocessed languages
like C and C++.

In some cases, AC_LANG_PROGRAM is already used but not sufficiently
m4-quoted, so we just need to add another set of [quotes] to prevent
the autoconf warning from being triggered bogusly.  Quoting all

fast-import: introduce "feature notes" command

Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.

When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.

Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op.  On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like

This version of fast-import does not support feature notes.

So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes.  (This would be especially important for backends that
do not support rewinding history after a botched import.)

 # However, if you remove everything, the rebase will be aborted.
 #

This does not make it clear that the format of each line is

<insn> <commit id> <explanatory text that will be printed>

but the reader will probably infer that from the automatically
generated pick examples above it.

What about the "exec" instruction?  By analogy, I might imagine that
the format of that line is "exec <command> <explanatory text>", and
the "x <cmd>" hint does not address that question (at first I read it
as taking an argument <cmd> that is the name of a shell).  Meanwhile,
the mention of <cmd> makes the hints harder to scan as a table.

So remove the <cmd> and add some words to remind the reader that
"exec" runs a command named by the rest of the line.  To make room, it
is left to the manpage to explain that that command is run using
$SHELL and that nonzero status from that command will pause the

Subject: setup: officially support --work-tree without --git-dir

The original intention of --work-tree was to allow people to work in a
subdirectory of their working tree that does not have an embedded .git
directory.  Because their working tree, which their $cwd was in, did not
have an embedded .git, they needed to use $GIT_DIR to specify where it is,
and because this meant there was no way to discover where the root level
of the working tree was, so we needed to add $GIT_WORK_TREE to tell git
where it was.

However, this facility has long been (mis)used by people's scripts to
start git from a working tree _with_ an embedded .git directory, let git
find .git directory, and then pretend as if an unrelated directory were
the associated working tree of the .git directory found by the discovery
process.  It happens to work in simple cases, and is not worth causing

Correctly report corrupted objects

The errno check added in commit 3ba7a06 "A loose object is not corrupt
if it cannot be read due to EMFILE" only checked for whether errno is
not ENOENT and thus incorrectly treated "no error" as an error
condition.

Because of that, it never reached the code path that would report that
the object is corrupted and instead caused funny errors like:

  fatal: failed to read object 333c4768ce595793fdab1ef3a036413e2a883853: Success

So we have to extend the check to cover the case in which the object
file was successfully read, but its contents are corrupted.
