Actually, I spent some time just now to improve the interface to git-diff-tree, allowing it to take a list of trees to compare from stdin.

And if you only give it one entry on stdin, it assumes it is a commit, and lists the tree difference between that and the parent(s). If it's a merge commit, it will ignore it unless you use "-m".

So now you can do

	git-rev-list HEAD --max-count=10 | git-diff-tree --stdin update-cache.c

to see which of the last 10 commits changed "update-cache.c".

And if you add the "-p" flag, it will show it as a diff too.

Damn, I'm good. It was just a few lines of code added to git-diff-tree.
