28bd70d811 unbreak and eliminate NO_C99_FORMAT
In the spirit of v1.5.0.2~21 (Check for PRIuMAX rather than
NO_C99_FORMAT in fast-import.c, 2007-02-20), use PRIuMAX from
git-compat-util.h on all platforms instead of C99-specific formats
like %zu with dangerous fallbacks to %u or %lu.

So now C99-challenged platforms can build git without provoking
warnings or errors from printf, even if pointers do not have the same
size as an int or long.

The need for a fallback PRIuMAX is detected in git-compat-util.h with
"#ifndef PRIuMAX".  So while at it, simplify the Makefile and configure
script by eliminating the NO_C99_FORMAT knob altogether.

31d713d069 mktag: avoid %td in format string
Since v1.7.0-rc0~34 (make "mktag" a built-in, 2010-01-22), git mktag
uses the C99-style %td format to print ptrdiff_t values.  It falls
back to %d when NO_C99_FORMAT is set, on the assumption that pre-C99
systems probably are using 32-bit pointers.

But many modern systems are 64-bit and

 * sometimes one wants to test the NO_C99_FORMAT fallbacks using a
   modern development platform;
 * some platforms (I'm looking at you, msvc) have not gotten with the
   program and are still C89-only.

These ptrdiff_t values are offsets from the beginning of a buffer, so
a size_t or uintmax_t would work about as well.  Use the latter so we
can take advantage of the PRIuMAX fallback in git-compat-util.h, even
on C99-challenged systems with 64-bit pointers.

3ba2e8653c stash: copy the index using --index-output instead of cp -p
'git stash create' must operate with a temporary index. For this purpose,
it used 'cp -p' to create a copy. -p is needed to preserve the timestamp
of the index file. Now Jakob Pfender reported a certain combination of
a Linux NFS client, OpenBSD NFS server, and cp implementation where this
operation failed.

Luckily, the first operation in git-stash after copying the index is to
call 'git read-tree'. Therefore, use --index-output instead of 'cp -p'
to write the copy of the index.

--index-output requires that the specified file is on the same volume as
the source index, so that the lock file can be rename()d. For this reason,
the name of the temporary index is constructed in a way different from the
other temporary files. The code path of 'stash -p' also needs a temporary
index, but we do not use the new name because it does not depend on the
same precondition as --index-output.

23a32ffe80 stash: fix incorrect quoting in cleanup of temporary files
The * was inside the quotes, so that the pattern was never expanded and the
temporary files were never removed. As a consequence, 'stash -p' left a
.git-stash-*-patch file in $GIT_DIR. Other code paths did not leave files
behind because they removed the temporary file themselves, at least in
non-error paths.

6affdbe677 gitweb: highlight: replace tabs with spaces
Consider the following code fragment:

        /*
         * test
         */

vim ":set list" mode shows that the first character on each line is a
tab:

^I/*$
^I * test$
^I */$

By default, the "highlight" program will retain the tabs in the HTML
output:

$ highlight --fragment --syntax c test.c
        <span class="hl com">/*</span>
<span class="hl com">    * test</span>
<span class="hl com">    */</span>

vim list mode:

^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$

In gitweb, this winds up looking something like:

   1         /*
   2     * test
   3     */

I tried both Firefox and Opera and saw the same behavior.

The desired output is:

   1         /*
   2          * test
   3          */

This can be accomplished by specifying "--replace-tabs=8" on the
highlight command line.

2cfe8a68cc diff --quiet: disable optimization when --diff-filter=X is used
The code notices that the caller does not want any detail of the changes
and only wants to know if there is a change or not by specifying --quiet.
And it breaks out of the loop when it knows it already found any change.

When you have a post-process filter (e.g. --diff-filter), however, the
path we found to be different in the previous round and set HAS_CHANGES
bit may end up being uninteresting, and there may be no output at the end.
The optimization needs to be disabled for such case.

Note that the f245194 (diff: change semantics of "ignore whitespace"
options, 2009-05-22) already disables this optimization by refraining
from setting HAS_CHANGES when post-process filters that need to inspect
the contents of the files (e.g. -S, -w) in diff_change() function.

b406a2d3e3 valgrind: ignore SSE-based strlen invalid reads
Some versions of strlen use SSE to speed up the calculation and load 4
bytes at a time, even if it means reading past the end of the
allocated memory. This read is safe and when the strlen function is
inlined, it is not replaced by valgrind, which reports a
false-possitive.

Tell valgrind to ignore this particular error, as the read is, in
fact, safe. Current upstream-released version 3.6.1 is affected. Some
distributions have this fixed in their latest versions.

808a95dcad diff --submodule: split into bite-sized pieces
Introduce two functions:

 - prepare_submodule_summary prepares the revision walker
   to list changes in a submodule.  That is, it:

   * finds merge bases between the commits pointed to this
     path from before ("left") and after ("right") the change;
   * checks whether this is a fast-forward or fast-backward;
   * prepares a revision walk to list commits in the symmetric
     difference between the commits at each endpoint.

   It returns nonzero on error.

 - print_submodule_summary runs the revision walk and saves
   the result to a strbuf in --left-right format.

The goal is just readability.  No functional change intended.

9cba13ca5d standardize brace placement in struct definitions
In a struct definitions, unlike functions, the prevailing style is for
the opening brace to go on the same line as the struct name, like so:

 struct foo {
	int bar;
	char *baz;
 };

Indeed, grepping for 'struct [a-z_]* {$' yields about 5 times as many
matches as 'struct [a-z_]*$'.

 is ...  well ...  inconsistent, but all right-thinking people know that
