[PATCH] gitk: show staged submodules regardless of ignore config

[Junio C Hamano <gitster@xxxxxxxxx>]

From: Jens Lehmann <Jens.Lehmann@xxxxxx>
Date: Tue, 8 Apr 2014 21:36:08 +0200

Currently setting submodule.<name>.ignore and/or diff.ignoreSubmodules to
"all" suppresses all output of submodule changes for gitk. This is really
confusing, as even when the user chooses to record a new commit for an
ignored submodule by adding it manually this change won't show up under
"Local changes checked in to index but not committed".

Fix that by using the '--ignore-submodules=dirty' option for both callers
of "git diff-index --cached" when the underlying git version supports that
option.

 * Paul, I've been carrying this in my 'pu' but I would prefer
   changes to gitk fed to me through you.  Could you apply this so
   that I can drop my tentative copy?

   Thanks.
