d1c3b10f7c git-rebase--interactive.sh: use printf instead of echo to print commit message
Replace the echo statements that operate on $rest with printf's to restore
what was lost from 938791cd.  This avoids any mangling that XSI-conformant
echo's may introduce.

2d6ca6ef55 git-rebase--interactive.sh: rework skip_unnecessary_picks
Commit cd035b1c introduced the exec command to interactive rebase.  In
doing so, it modified the way that skip_unnecessary_picks iterates through
the list of rebase commands so that it avoided collapsing multiple spaces
into a single space.  This is necessary for example if the argument to the
exec command contains a path with multiple spaces in it.

The way it did this was by reading each line of rebase commands into a
single variable, and then breaking the individual components out using
echo, sed, and cut.  It used the individual broken-out components for
decision making, and was still able to write the original line to the
output file from the variable it had saved it in.  But, since we only
really need to look at anything other than the first element of the line
when a 'pick' command is encountered, and even that is only necessary when
we are still searching for "unnecessary" picks, and since newer rebase
commands like 'exec' may not even require a sha1 field, let's make our read
statement parse its input into a "command" variable, and a "rest" variable,
and then only break out the sha1 from $rest, and call git-rev-parse, when
absolutely necessary.

I think this future proofs this subroutine, avoids calling git-rev-parse
unnecessarily, and possibly with bogus arguments, and still accomplishes
the goal of not mangling the $rest of the rebase command.

44c48a909a diff --follow: do call diffcore_std() as necessary
Usually, diff frontends populate the output queue with filepairs without
any rename information and call diffcore_std() to sort the renames out.
When --follow is in effect, however, diff-tree family of frontend has a
hack that looks like this:

    diff-tree frontend
    -> diff_tree_sha1()
       . populate diff_queued_diff
       . if --follow is in effect and there is only one change that
         creates the target path, then
       -> try_to_follow_renames()
	  -> diff_tree_sha1() with no pathspec but with -C
	  -> diffcore_std() to find renames
	  . if rename is found, tweak diff_queued_diff and put a
	    single filepair that records the found rename there
    -> diffcore_std()
       . tweak elements on diff_queued_diff by
       - rename detection
       - path ordering
       - pickaxe filtering

We need to skip parts of the second call to diffcore_std() that is related
to rename detection, and do so only when try_to_follow_renames() did find
a rename.  Earlier 1da6175 (Make diffcore_std only can run once before a
diff_flush, 2010-05-06) tried to deal with this issue incorrectly; it
unconditionally disabled any second call to diffcore_std().

This hopefully fixes the breakage.

39f75d26e2 diff --follow: do not waste cycles while recursing
The "--follow" logic is called from diff_tree_sha1() function, but the
input trees to diff_tree_sha1() are not necessarily the top-level trees
(compare_tree_entry() calls it while it recursively descends into
subtrees).  When a newly created path lives in somewhere deep in the
source hierarchy, e.g. "platform/", but the rename source is in a totally
different place in the destination hierarchy, e.g. "lang-api/src/com/...",
running "try_to_find_renames()" while base is set to "platform/" is a
wasted call.

We only need to run the rename following at the very top level.

fa57f717cd perl/Makefile: Unset INSTALL_BASE when making perl.mak
PREFIX and INSTALL_BASE are mutually exclusive. If both are supplied
by INSTALL_BASE being set in PERL_MM_OPT ExtUtils::MakeMaker will
produce an error:

    $ echo $PERL_MM_OPT
    INSTALL_BASE=/home/avar/perl5
    $ make -C perl  PERL_PATH='/usr/bin/perl' prefix='/home/avar' perl.mak
    make: Entering directory `/home/avar/g/git/perl'
    /usr/bin/perl Makefile.PL PREFIX='/home/avar'
    Only one of PREFIX or INSTALL_BASE can be given.  Not both.
    make: *** [perl.mak] Error 255
    make: Leaving directory `/home/avar/g/git/perl'

Change the perl Makefile to work around this by explicitly unsetting
INSTALL_BASE.

INSTALL_BASE is set in PERL_MM_OPT by e.g. the popular local::lib
package, from its documentation:

    eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib 2>/dev/null)

Many other environments might also have set PERL_MM_OPT before
building Git. This change enables us to build in these environments.

cf65426de6 pull --rebase: Avoid spurious conflicts and reapplying unnecessary patches
Prior to c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), pull --rebase would run

  git rebase $merge_head

which resulted in a call to

  git format-patch ... --ignore-if-in-upstream $merge_head..$cur_branch

This resulted in patches from $merge_head..$cur_branch being applied, as
long as they did not already exist in $cur_branch..$merge_head.

Unfortunately, when upstream is rebased, $merge_head..$cur_branch also
refers to "old" commits that have already been rebased upstream, meaning
that many patches that were already fixed upstream would be reapplied.
This could result in many spurious conflicts, as well as reintroduce
patches that were intentionally dropped upstream.

So the algorithm was changed in c85c792 (pull --rebase: be cleverer with
rebased upstream branches, 2008-01-26) and d44e712 (pull: support rebased
upstream + fetch + pull --rebase, 2009-07-19).  Defining $old_remote_ref to
be the most recent entry in the reflog for @{upstream} that is an ancestor
of $cur_branch, pull --rebase was changed to run

  git rebase --onto $merge_head $old_remote_ref

which results in a call to

  git format-patch ... --ignore-if-in-upstream $old_remote_ref..$cur_branch

The whole point of this change was to reduce the number of commits being
reapplied, by avoiding commits that upstream already has or had.

In the rebased upstream case, this change achieved that purpose.  It is
worth noting, though, that since $old_remote_ref is always an ancestor of
$cur_branch (by its definition), format-patch will not know what upstream
is and thus will not be able to determine if any patches are already
upstream; they will all be reapplied.

In the non-rebased upstream case, this new form is usually the same as the
original code but in some cases $old_remote_ref can be an ancestor of

   $(git merge-base $merge_head $cur_branch)

meaning that instead of avoiding reapplying commits that upstream already
has, it actually includes more such commits.  Combined with the fact that
format-patch can no longer detect commits that are already upstream (since
it is no longer told what upstream is), results in lots of confusion for
users (e.g. "git is giving me lots of conflicts in stuff I didn't even
change since my last push.")

Cases where additional commits could be reapplied include forking from a
commit other than the tracking branch, or amending/rebasing after pushing.
Cases where the inability to detect upstreamed commits cause problems
include independent discovery of a fix and having your patches get
upstreamed by some alternative route (e.g. pulling your changes to a third
machine, pushing from there, and then going back to your original machine
and trying to pull --rebase).

Fix the non-rebased upstream case by ignoring $old_remote_ref whenever it
is contained in $(git merge-base $merge_head $cur_branch).  This should
have no affect on the rebased upstream case.

Walking forward through history (i.e., topologically earliest
commits first), we filter the parent list of every commit as
follows. Consider a parent P:
 - If P touches any of the interesting line ranges, we keep it.
 - If P is a merge and it takes all the interesting line ranges
   from one of its parents, P is rewritten to this parent, else
   we keep P.
 - Otherwise, P is rewritten to its (only) parent P^.

The new t020[01] for gettext support did not find git-sh-i18n and the
translation data when run under --valgrind: lib-gettext.sh tried to
locate them under $GIT_EXEC_PATH, which normally is the git build
directory, but is changed by --valgrind to point to the wrappers.

Introduce a new variable $GIT_BUILD_DIR which can be used to locate
data that resides under the build directory, and use that instead.

107880a701 gettext: setlocale(LC_CTYPE, "") breaks Git's C function assumptions
Remove the setlocale/LC_CTYPE call from gettext.c, we only need
setlocale/LC_MESSAGES to use the message catalog, and setting LC_CTYPE
from the environment breaks Git's assumptions about C library
functions.

Under a non-C locale functions like vsnprintf become locale sensitive,
so that they'll e.g. refuse to process ISO-8895-1 data under a UTF-8
locale.

This triggered a "your vsnprintf is broken" error on Git's own
repository when inspecting v0.99.6~1 under a UTF-8 locale.

That commit contains a ISO-8859-1 encoded author name, which the
locale aware vsnprintf(3) won't interpolate in the format argument,
due to mismatch between the data encoding and the locale.
