When we showed the initial commit, we had no reference to
diff against, so we went through the cache manually.
Nowadays, however, we have a virtual empty tree commit, so
we can simply diff against that to get the same results.

I ran across this when I realized I could do the same trick for the
verbose diff (which I will do in the next patch). I think it is a
worthwhile cleanup. Not only does it remove a lot of lines, but it gives
a single codepath for printing, which will be helpful if that codepath
ever changes (e.g., with the alternate status formats we talked about a
few weeks ago).
This could be made even simpler by setting s->reference to the empty
tree when we are on the initial commit, but I think that is a little
messy. The caller may have set s->reference to an arbitrary pointer,
including one which needs free()d, and we would be overwriting that.
As it happens, with the current callers there is no problem, but it
seems like a bad interface.
