Let --decorate show HEAD position

trast · gitster · commit 77abcbdc268d · 2009-10-12T16:22:35.000-07:00
'git log --graph --oneline --decorate --all' is a useful way to get a
general overview of the repository state, similar to 'gitk --all'.
Let it indicate the position of HEAD by loading that ref too, so that
the --decorate code can see it.
