Rewrite java.util.Formatter documentation.

Some guy on the internets pointed out that our documentation of argument
indexes was garbled. I fixed that, and then noticed that pretty much all
the documentation was close enough to be convincing but wrong enough to
not be very useful.

I've fixed everything I've found. The result isn't perfect, but it's good
enough that I could stand to use it myself now.
