Update working tree files fully atomically

Browse source 
This avoids commit churn by the assistant when eg,
replacing a file with a symlink.

But, just as importantly, it prevents the working tree being left with a
deleted file if git-annex, or perhaps the whole system, crashes at the
wrong time.

(It also probably avoids confusing displays in file managers.)
