When I worked with index the first time, I had difficulty knowing what was in index. Index is, unlike working directory, intangible. I could use git-diff (and actually did), but it was still better if I could have seen what exactly was in index.

To me, index and object database are (to some extent) the same: both are used to store files. If I can examine git object database, why not index?

About adding index support to git-show, yes it's really messy. index doesn't have tree objects. If a user wants to list a subdirectory in index, git-show will have to do more work, I think. Perhaps we should forget this for now.
