Subject: [PATCH 1/4] difftool--helper: Make style consistent with git
Use the predominant conditional style where "then" appears
alone on the line after the test expression.

Subject: [PATCH 2/4] mergetool--lib: Make style consistent with git
Use the predominant conditional style where "then" appears
alone on the line after the test expression.
Remove spaces after ">" output redirections.
Remove unnecessary parentheses around the kdiff3 commands.

Subject: [PATCH 3/4] mergetool--lib: Refactor tools into separate files
Individual merge tools are now defined in a mergetools/$tool
file which is sourced at runtime.
The individual files are installed into $(git --exec-path)/mergetools/.
New tools can be added by creating a new file instead of editing the
git-mergetool--lib.sh scriptlet.

From f61bd9c68a4ed81afcc1fbbf5b956e781d88b434 Mon Sep 17 00:00:00 2001
From: David Aguilar <davvid@gmail.com>
Date: Fri, 19 Aug 2011 02:14:45 -0700
Subject: [PATCH 4/4] mergetools/meld: Use '--output' when available
meld 1.5.0 and newer allow the output file to be specified
when merging multiple files. Check whether the meld command
supports '--output' and use it when available.
