Re: [PATCH] Make git-diff-tree indicate when it flushes

There are times when gitk needs to know that the commits it has sent
to git-diff-tree --stdin did not match, and it needs to know in a
timely fashion even if none of them match.  At the moment,
git-diff-tree outputs nothing for non-matching commits, so it is
impossible for gitk to distinguish between git-diff-tree being slow
and git-diff-tree saying no.

Wouldn't this help?

	$ git-diff-tree --stdin --always

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?

Paul.
