Apparently I was under a rock sleeping when git-tag-script changed to no longer take input from stdin. So my script which did:

TAG=$(echo "$TAG_MSG" | git-tag-script $RELEASE) echo $TAG > .git/refs/tags/$RELEASE

Is broken in two ways. First it's no longer building an annotated tag, second it creaets a zero length file .git/refs/tags/$RELEASE. Second issue is trivial to fix in my script. First one needs some change in the tag script. Below is a simple patch for a stab at fixing.

Allow users to create a tag message by passing message on command line instead of requiring an $EDITOR session.
