ametzler@merulo:/tmp/GIT/git-core-1.6.6-debug/t/trash directory.t1001-read-tree-m-2way$ <M.out /tmp/GIT/git-core-1.6.6-debug/git-is-binary M.out 4.out
static buffer is not binary
stdin is not binary
M.out is binary
4.out is not binary

ametzler@merulo:/tmp/GIT/git-core-1.6.6-debug/t/trash directory.t1001-read-tree-m-2way$ /tmp/GIT/git-core-1.6.6-debug/git-diff --no-index M.out 4.out
a/M.out is binary
b/4.out is binary
diff --git a/M.out b/4.out
index 4aefa95..d5ec90a 100644
Binary files a/M.out and b/4.out differ

FWIW all versions of git-diff I tried (1.6.6, 1.6.5, and
report "Binary files a/M.out and b/4.out differ".
