That way, it doesn't care how the refs are stored any more Signed-off-by: Linus Torvalds <torvalds@osdl.org> --- Just as an example of how to use git-show-ref rather than knowing about "$GIT_DIR/refs/..." paths. This basically replaces my much hackier version that is in the "lt/refs" branch, but can go into the master branch independently of the refs-packing work.
