I have checked it int the gitweb at

As far as I can see that is single patch (single commit) on top of git.git repository, so you could have send this patch to the list, to be commented upon.

Although having "git submodule diff" is quite nice, I'd rather have "git diff --recurse-submodules" (or something like that) if I want to get diff of submodules.

I'd like to mention that instead of

  (unset GIT_DIR && cd "$path" && git diff $flag "$sha1..HEAD")

you can simply use

  git --git-dir="$path" diff $flag "$sha1..HEAD"

Note that you can write "$sha1.." (but it is a bit cryptic)

You can always read list using NNTP / news / Usenet interface at
