Handle fresh empty repository.

Browse source 
It was imposible to see what was staged for a first commit on a fresh
git repository. The only visible lines was fatal error messages from
git. Now diff against null tree object is shown in magit status buffer
if nothing was yet commited to the repository. The cost is 15-byte
object added to the repo, but it shuld disappear on first call to git
gc.
