On the git.git tree:

$ cat revs 65aadb92a1ce9605fa2f412b51de91781a3ef3d6 cc189c2ca2c725c430f100f61e7c4a6849f93163 $ git diff-tree -r -s --stdin -- apply.c <revs 65aadb92a1ce9605fa2f412b51de91781a3ef3d6 $ git diff-tree -r -s --stdin --always -- apply.c <revs 65aadb92a1ce9605fa2f412b51de91781a3ef3d6 cc189c2ca2c725c430f100f61e7c4a6849f93163 $

With --always, how do I tell that 65aadb affects apply.c and cc189c doesn't?
