Subject: gitk: Make "find" on "Files" work again.
X-Git-Tag: v1.3.0-rc1~161^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=69d47bdd6c1d6cb9c8603fd1da8b756e2903f955;p=git.git

gitk: Make "find" on "Files" work again.

It was broken by the change to supply just the child id to
git-diff-tree rather than both child and parent.
