[PATCH 3/3] Rename git-diff-tree-helper to git-diff-helper (part 2). It used to be that diff-tree needed helper support to parse its raw output to generate diffs, but these days git-diff-* family produces the same output and the helper is not tied to diff-tree anymore. Drop "tree" from its name. This follows the "rename only" commit to adjust the contents of the files involved. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Petr Baudis <pasky@ucw.cz>

git-diff-helper - Generates patch format output for git-diff-*
[PATCH 1/4] split core-git.txt and update Split the core-git.txt file Formatting fix to the diff-format.txt Signed-off-by: David Greaves <david@dgreaves.com>

SYNOPSIS
--------
[PATCH] Detect renames in diff family. This rips out the rename detection engine from diff-helper and moves it to the diff core, and updates the internal calling convention used by diff-tree family into the diff core. In order to give the same option name to diff-tree family as well as to diff-helper, I've changed the earlier diff-helper '-r' option to '-M' (stands for Move; sorry but the natural abbreviation 'r' for 'rename' is already taken for 'recursive'). Although I did a fair amount of test with the git-diff-tree with existing rename commits in the core GIT repository, this should still be considered beta (preview) release. This patch depends on the diff-delta infrastructure just committed. This implements almost everything I wanted to see in this series of patch, except a few minor cleanups in the calling convention into diff core, but that will be a separate cleanup patch.

DESCRIPTION
-----------
Reads output from "git-diff-cache", "git-diff-tree" and "git-diff-files" and
generates patch format output.
OPTIONS
-------
-z::
\0 line termination on input
-R::
Output diff in reverse. This is useful for displaying output from
"git-diff-cache" which always compares tree with cache or working
file. E.g.

[PATCH] Diff-helper update This patch adds a framework and a stub implementation of rename detection to diff-helper program. The current stub code is just enough to detect pure renames in diff-tree output and not fancier. The plan is perhaps to use the same delta code when Nico's delta storage patch is merged for similarity evaluation purposes.
