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.

Git's diff machinery has supported a -s (silence diff output) option
as far back as v0.99~900 (Silent flag for show-diff, 2005-04-13), but
the option is only advertised in an odd corner of the git diff-tree
manual.
The main use is to retrieve basic metadata about a commit:
git show -s rev
Explain this in the 'git log' manual and provide an example in the
'git show' examples section. This is kind of a cop-out, since it
would be more useful to explain it in the 'git show' manual proper,
which says:
The command takes options applicable to the git
diff-tree command to control how the changes the
commit introduces are shown.
This manual page describes only the most frequently
used options.
Fixing that is a larger task for another day.
