Almost updated completion for GNU du

[Mikael Magnusson <mikachu@xxxxxxxxx>]

This almost works, well, it does work. But if you swap the order of
the --time and --time-style lines, --time-style stops working, ie
--time-style=<tab> produces no completions. Can anyone explain this?
I've tried in zsh -f.
