The plumbing "diff" commands look at the working tree files without
refreshing the index themselves for performance reasons (the calling
script is expected to do that upfront just once, before calling one or
more of them). In the early days of git, they showed the "diff --git"
header before they actually ask the xdiff machinery to produce patches,
and ended up showing only these headers if the real contents are the same
and the difference they noticed was only because the stat info cached in
the index did not match that of the working tree. It was too late for the
implementation to take the header that it already emitted back.
But 3e97c7c (No diff -b/-w output for all-whitespace changes, 2009-11-19)
introduced necessary logic to keep the meta-information headers in a
strbuf and delay their output until the xdiff machinery noticed actual
changes. This was primarily in order to generate patches that ignore
whitespaces. When operating under "-w" mode, we wouldn't know if the
header is needed until we actually look at the resulting patch, so it was
a sensible thing to do, but we did not realize that the same reasoning
applies to stat-dirty paths.
Later, 296c6bb (diff: fix "git show -C -C" output when renaming a binary
file, 2010-05-26) generalized this machinery and added must_show_header
toggle. This is turned on when the header must be shown even when there
is no patch to be produced, e.g. only the mode was changed, or the path
was renamed, without changing the contents. However, when it did so, it
still kept the special case for the "-w" mode, which meant that the
plumbing would keep showing these phantom changes.
This corrects this historical inconsistency by allowing the plumbing to
omit paths that are only stat-dirty from its output in the same way as it
handles whitespace only changes under "-w" option.
The change in the behaviour can be seen in the updated test.

The plumbing that looks at the working tree, i.e. "diff-index" and
"diff-files", always emit the "diff --git a/path b/path" header lines
without anything else for paths that are only stat-dirty (i.e. different
only because the cached stat information in the index no longer matches
that of the working tree, but the real contents are the same), when
these commands are run with "-p" option to produce patches.
Illustrate this current behaviour. Also demonstrate that with the "-w"
option, we (correctly) hold off showing a "diff --git" header until actual
differences have been found. This also suppresses the header for merely
stat-dirty files, which is inconsistent.

Match the style to more modern test scripts, namely:
- The first line of each test has prereq, title and opening sq for the
script body. This makes the test shorter while reducing the need for
backslashes.
- Be prepared for the case in which the previous test may have failed.
If a test wants to start from not having "frotz" that the previous test
may have created, write "rm -f frotz", not "rm frotz".
- Prepare the expected output inside your own test.
- The order of comparison to check the result is "diff expected actual",
so that the output will show how the output from the git you just broke
is different from what is expected.
- Write no SP between redirection '>' (or '<' for that matter) and the
filename.

Split the "message in editor has initial comment" test into three
tests. The motivation is to be able to only skip the middle part under
NO_GETTEXT_POISON.
In addition the return value of 'git tag' was being returned. We now
check that it's non-zero. I used ! instead of test_must_fail so that
the GIT_EDITOR variable was only used in this command invocation, and
because the surrounding tests use this style.

v1.7.3-rc0~75^2 (Teach fast-import to import subtrees named by tree id,
2010-06-30) has a shortcoming - it doesn't allow the root to be set.
Extend this behaviour by allowing the root to be referenced as the
empty path, "".
For a command (like filter-branch --subdirectory-filter) that wants
to commit a lot of trees that already exist in the object db, writing
undeltified objects as loose files only to repack them later can
involve a significant amount of overhead.
(23% slow-down observed on Linux 2.6.35, worse on Mac OS X 10.6)
Fortunately we have fast-import (which is one of the only git commands
that will write to a pack directly) but there is not an advertised way
to tell fast-import to commit a given tree without unpacking it.
This patch changes that, by allowing
M 040000 <tree id> ""
as a filemodify line in a commit to reset to a particular tree without
any need to parse it. For example,
M 040000 4b825dc642 ""
is a synonym for the deleteall command and the fast-import equivalent of
git read-tree 4b825dc642

Upon program invocation, MSYS converts environment variables containing
path-like values from Unix-style to DOS-style under the assumption that
the program being invoked understands only DOS-style pathnames. For
instance, the Unix-style path /msysgit is translated to c:/msysgit. For
test t5560, the path being requested from git-http-backend is specified
via environment variable PATH_INFO as a URL path of the form
/repo.git/foobar, which git-http-backend combines with GIT_PROJECT_ROOT
to determine the actual physical path within the repository. This is a
case where MSYS's conversion of the path-like value of PATH_INFO causes
harm, for two reasons. First, the resulting converted path, when joined
with GIT_PROJECT_ROOT is bogus (for instance,
"C:/msysgit/git/t/trash-zzz/C:/msysgit/repo.git/HEAD"). Second, the
converted PATH_INFO path is rejected by git-http-backend as an 'alias'
due to validation failure on the part of daemon_avoid_alias().
Unfortunately, the standard work-around of doubling the leading slash
(i.e. //repo.git/foobar) to suppress MSYS path conversion works only for
command-line arguments, but not for environment variables.
Consequently, side step the problem by instead passing git-http-backend
an already-constructed full path rather than components GIT_PROJECT_ROOT
and PATH_INFO.

By default, MSYS sed throws away CR from CRLF line-endings. Tests
t6038.5 and t6038.6 employ sed to normalize conflict output of git-merge
for validation purposes. These tests expect CRLF line-endings to be
present in the normalized output of git-merge, and thus fail when sed
undesirably removes CR. Fix by employing sed's -b/--binary switch to
suppress its default behavior of dropping CR characters.

These two tests fail on msysGit because /dev/null is an alias for nul on
Windows and when reading the value back from git config the alias does
not match the real filename. Also the HOME environment variable has a

these are platform-dependent equivalent results it seems simplest to
skip the test entirely.

It's a minor annoyance when you take the painstaking time to setup To:
headers for each patch in a large series, and then go out to send the
series with git-send-email and watch git ignore the To: headers in the
patch files.
Therefore, always add To: headers from a patch file to the To: headers
for that message. Keep the prompt for the blanket To: header so as to
not break scripts (and user expectations). This means even if a patch
has a To: header, git will prompt for the To: address. Otherwise, we'll
need to introduce interface breakage to either request the header for
each patch missing a To: header or default the header to whatever To:
address is found first (be it in a patch or from user input). Both of
these options don't seem very obvious/useful.
