c425d361f5 Merge branch 'en/combined-all-paths'
Output from "diff --cc" did not show the original paths when the
merge involved renames.  A new option adds the paths in the
original trees to the output.

d76ce4f734 log,diff-tree: add --combined-all-paths option
The combined diff format for merges will only list one filename, even if
rename or copy detection is active.  For example, with raw format one
might see:

  ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM	describe.c
  ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM	bar.sh
  ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR	phooey.c

This doesn't let us know what the original name of bar.sh was in the
first parent, and doesn't let us know what either of the original names
of phooey.c were in either of the parents.  In contrast, for non-merge
commits, raw format does provide original filenames (and a rename score
to boot).  In order to also provide original filenames for merge
commits, add a --combined-all-paths option (which must be used with
either -c or --cc, and is likely only useful with rename or copy
detection active) so that we can print tab-separated filenames when
renames are involved.  This transforms the above output to:

  ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM	desc.c	desc.c	desc.c
  ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM	foo.sh	bar.sh	bar.sh
  ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR	fooey.c	fuey.c	phooey.c

Further, in patch format, this changes the from/to headers so that
instead of just having one "from" header, we get one for each parent.
For example, instead of having

  --- a/phooey.c
  +++ b/phooey.c

we would see

  --- a/fooey.c
  --- a/fuey.c
  +++ b/phooey.c

9fce19a431 diff-tree doc: correct & remove wrong documentation
The documentation saying that diff-tree didn't support anything except
literal prefixes hasn't been true since
d38f28093e ("tree_entry_interesting(): support wildcard matching",
2010-12-15), but this documentation was not updated at the time.

Since this command uses pathspecs like most other commands, there's no
need to show examples of how the various "cmd <revs> <paths>"
invocations work.

Furthermore, the "git diff-tree --abbrev 5319e4" example shown here
never worked. We'd ended up with that through a combination of
62b42d3487 ("docs: fix some antique example output", 2011-05-26) and
ac4e086929 ("Adjust core-git documentation to more recent Linus GIT.",
2005-05-05), but "git diff-tree <tree>" was always invalid.

76a8788c14 doc: keep first level section header in upper case
When formatted as a man page, 1st section header is always in upper
case even if we write it otherwise. Make all 1st section headers
uppercase to keep it close to the final output.

This does affect html since case is kept there, but I still think it's
a good idea to maintain a consistent style for 1st section headers.

Some sections perhaps should become second sections instead, where
case is kept, and for better organization. I will update if anyone has
suggestions about this.

While at there I also make some header more consistent (e.g. examples
vs example) and fix a couple minor things here and there.

48bb914ed6 doc: drop author/documentation sections from most pages
The point of these sections is generally to:

  1. Give credit where it is due.

  2. Give the reader an idea of where to ask questions or
     file bug reports.

But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame.  For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.

So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.

Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

0b444cdb19 Documentation: spell 'git cmd' without dash throughout
The documentation was quite inconsistent when spelling 'git cmd' if it
only refers to the program, not to some specific invocation syntax:
both 'git-cmd' and 'git cmd' spellings exist.

The current trend goes towards dashless forms, and there is precedent
in 647ac70 (git-svn.txt: stop using dash-form of commands.,
2009-07-07) to actively eliminate the dashed variants.

Replace 'git-cmd' with 'git cmd' throughout, except where git-shell,
git-cvsserver, git-upload-pack, git-receive-pack, and
git-upload-archive are concerned, because those really live in the
$PATH.

140b378d07 Teach git diff-tree --stdin to diff trees
When feeding trees on the command line, you can give exactly two
trees, not three nor one; --stdin now supports this "two tree" form on
its input, in addition to accepting lines with one or more commits.

When diffing trees (either specified on the command line or from the
standard input), the -s, -v, --pretty, --abbrev-commit, --encoding,
--no-commit-id, and --always options are ignored, since they do not
apply to trees; and the -m, -c, and --cc options are ignored since
they would be meaningful only with three or more trees, which is not
supported (yet).

eabbc99a21 fix diff-tree --stdin documentation
Long time ago, the feature of "diff-tree --stdin" to take a commit and its
parents on one line was broken, and did not support the common:

    git rev-list --parents $commits... -- $paths... |
    git diff-tree --stdin -v -p

usage pattern by Porcelains properly.  For diff-tree to talk sensibly
about commits, it needs to see commits, not just trees; the code was fixed
to take list of commits on the standard input in 1.2.0.

However we left the documentation stale for a long time, until Karl
Hasselström finally noticed it very recently.

b1889c36d8 Documentation: be consistent about "git-" versus "git "
Since the git-* commands are not installed in $(bindir), using
"git-command <parameters>" in examples in the documentation is
not a good idea. On the other hand, it is nice to be able to
refer to each command using one hyphenated word. (There is no
escaping it, anyway: man page names cannot have spaces in them.)

This patch retains the dash in naming an operation, command,
program, process, or action. Complete command lines that can
be entered at a shell (i.e., without options omitted) are
made to use the dashless form.

The changes consist only of replacing some spaces with hyphens
and vice versa. After a "s/ /-/g", the unpatched and patched
versions are identical.

This default regex now matches explicit values, and unfortunately in this
case gitlink was being matched by just 'link', causing the wrong inline
macro template to be applied. By renaming the macro, we can avoid being
matched by the wrong regex.

215a7ad1ef Big tool rename.
As promised, this is the "big tool rename" patch.  The primary differences
since 0.99.6 are:

  (1) git-*-script are no more.  The commands installed do not
      have any such suffix so users do not have to remember if
      something is implemented as a shell script or not.

  (2) Many command names with 'cache' in them are renamed with
      'index' if that is what they mean.

There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support  is expected to be removed in the near
future.

ce24067549 [PATCH] diff: Fix docs and add -O to diff-helper.
This patch updates diff documentation and usage strings:

 - clarify the semantics of -R.  It is not "output in reverse";
   rather, it is "I will feed diff backwards".  Semantically
   they are different when -C is involved.

 - describe -O in usage strings of diff-* brothers.  It was
   implemented, documented but not described in usage text.

Also it adds -O to diff-helper.  Like -S (and unlike -M/-C/-B),
this option can work on sanitized diff-raw output produced by
the diff-* brothers.  While we are at it, the call it makes to
diffcore is cleaned up to use the diffcore_std() like everybody
else, and the declaration for the low level diffcore routines
are moved from diff.h (public) to diffcore.h (private between
diff.c and diffcore backends).

af5323e027 [PATCH] Add -O<orderfile> option to diff-* brothers.
A new diffcore filter diffcore-order is introduced.  This takes
a text file each of whose line is a shell glob pattern.  Patches
that match a glob pattern on an earlier line in the file are
output before patches that match a later line, and patches that
do not match any glob pattern are output last.

A typical orderfile for git project probably should look like
this:

    README
    Makefile
    Documentation
    *.h
    *.c

f345b0a066 [PATCH] Add -B flag to diff-* brothers.
A new diffcore transformation, diffcore-break.c, is introduced.

When the -B flag is given, a patch that represents a complete
rewrite is broken into a deletion followed by a creation.  This
makes it easier to review such a complete rewrite patch.

The -B flag takes the same syntax as the -M and -C flags to
specify the minimum amount of non-source material the resulting
file needs to have to be considered a complete rewrite, and
defaults to 99% if not specified.

As the new test t4008-diff-break-rewrite.sh demonstrates, if a
file is a complete rewrite, it is broken into a delete/create
pair, which can further be subjected to the usual rename
detection if -M or -C is used.  For example, if file0 gets
completely rewritten to make it as if it were rather based on
file1 which itself disappeared, the following happens:

    The original change looks like this:

	file0     --> file0' (quite different from file0)
	file1     --> /dev/null

    After diffcore-break runs, it would become this:

	file0     --> /dev/null
	/dev/null --> file0'
	file1     --> /dev/null

    Then diffcore-rename matches them up:

	file1     --> file0'

The internal score values are finer grained now.  Earlier
maximum of 10000 has been raised to 60000; there is no user
visible changes but there is no reason to waste available bits.

e25de75696 [PATCH] Pickaxe fixes.
A bug in the command line argument parsing code was making
pickaxe not to work at all in diff-cache and diff-files commands.
Embarrassingly enough, the working pickaxe in diff-tree tells me
that it was not working in these two commands from day one.
This patch fixes it.

Also updates the documentation to describe the --pickaxe-all option.
