doc/log: correct default for --decorate

There're two different default options for log --decorate:
* Should `--decorate` be given without any arguments, it's default to
  `short`
* Should neither `--decorate` nor `--no-decorate` be given, it's default
  to the `log.decorate` or `auto`.

We documented the former, but not the latter.

Let's document them, too.
