fix diff-tree --stdin documentation
Long time ago, the feature of "diff-tree --stdin" to take a commit and its parents on one line was broken, and did not support the common: git rev-list --parents $commits... -- $paths... | git diff-tree --stdin -v -p usage pattern by Porcelains properly. For diff-tree to talk sensibly about commits, it needs to see commits, not just trees; the code was fixed to take list of commits on the standard input in 1.2.0. However we left the documentation stale for a long time, until Karl Hasselström finally noticed it very recently. Signed-off-by: Junio C Hamano <gitster@pobox.com>
