When the file is binary, it is listed in the diffstat, otherwise it is not. For example: | mj@albireo:/tmp$ mkdir gt | mj@albireo:/tmp$ cd gt | mj@albireo:/tmp/gt$ git init | Initialized empty Git repository in /tmp/gt/.git/ | mj@albireo:/tmp/gt$ echo abcdef >a | mj@albireo:/tmp/gt$ dd if=/dev/zero of=b bs=1024 count=1 | 1+0 records in | 1+0 records out | 1024 bytes (1.0 kB) copied, 7.3243e-05 s, 14.0 MB/s | mj@albireo:/tmp/gt$ git add * | mj@albireo:/tmp/gt$ git commit -m 'adding' | [master (root-commit) 295d5f9] adding | 2 files changed, 1 insertions(+), 0 deletions(-) | create mode 100644 a | create mode 100644 b | mj@albireo:/tmp/gt$ chmod 755 * | mj@albireo:/tmp/gt$ git add * | mj@albireo:/tmp/gt$ git commit -m 'chmoding' | [master 61c251b] chmoding | 1 files changed, 0 insertions(+), 0 deletions(-) | mode change 100644 => 100755 a | mode change 100644 => 100755 b | mj@albireo:/tmp/gt$ git diff HEAD^ | diff --git a/a b/a | old mode 100644 | new mode 100755 | diff --git a/b b/b | old mode 100644 | new mode 100755 | mj@albireo:/tmp/gt$ git diff --stat HEAD^ | b | Bin 1024 -> 1024 bytes | 1 files changed, 0 insertions(+), 0 deletions(-) This happens in git-1.7.6 and in several older versions as well. Am I missing something or is it a bug?
