Improve documentation for OptionParser
The documentation for OptionParser should be improved.
The current examples and and documentation do not yet describe
how to access non option args
I suggest to change the simple example in the doc as follows:
opts.banner = "Usage: example.rb [options] file ..."
p "files:" + ARGV
It should be stated explicitely in the description,
that parse! modifies the ARGV and removes all parseable args.
At least that is how I believe that the OptionParser.parse! works?
not yet tried it myself

I tried to make this clearer, see patch.
I also changed the example to avoid a warning for "shadowed outer local variable".
@zzak: Do you think that the "Further documentation" section is of any use in the current form (since changeset r36960)? I would suggest to remove it completely, since filing a ticket for usage questions seems not the right thing to do.

Eike, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.

Thanks Marcus, I was holding off on this until I got around to some other patches I have in mind for OptionParser, but you beat me to it :)
Re: remove further documentation: I think we should keep it, it doesn't hurt to mention the tracker if anyone comes across any bugs it will probably be documentation related when reading the optparse docs.
