showing conflicting merges

Hello,

There is a thread on the linux-arm-kernel ML that discusses handling of merge conflicts with git.[1]

I played around a bit with that and wondered about a few things:

	ukleinek@zentaur:~/gsrc/linux-2.6$ git checkout -b test adf6d34e460387ee3e8f1e1875d
	Switched to a new branch "test"

	ukleinek@zentaur:~/gsrc/linux-2.6$ git merge v2.6.25
	Auto-merged MAINTAINERS
	CONFLICT (delete/modify): drivers/leds/leds-tosa.c deleted in HEAD and modified in v2.6.25. Version v2.6.25 of drivers/leds/leds-tosa.c left in tree.
	Auto-merged drivers/serial/imx.c
	Automatic merge failed; fix conflicts and then commit the result.

Now "git diff --merge" shows:

	diff --cc drivers/leds/leds-tosa.c
	index 7ebecc4,0000000..9e0a188
	...

Shouldn't that better be reversed, i.e. 9e0a188..7ebecc4,0000000?

The resolution was to delete drivers/leds/leds-tosa.c:

	ukleinek@zentaur:~/gsrc/linux-2.6$ git rm drivers/leds/leds-tosa.c
	rm 'drivers/leds/leds-tosa.c'
	rm 'drivers/leds/leds-tosa.c'

	ukleinek@zentaur:~/gsrc/linux-2.6$ git commit
	Created commit 99a64ab: Merge commit 'v2.6.25' into test

Now "git show" doesn't show the conflict resolution as it does for other conflicting merges. Adding -p and/or --cc didn't help either. Looking at the source I think the problem is that diff_tree_combined only shows diffs for paths that are touched by every parent. I'm not sure how I want to have the diff shown, but showing nothing seems wrong. Ideas?

Another thing is that rerere don't record my resolution.

Best regards Uwe
