block parameter for "execute" about slop

[leejarvis]

Hi Stefan!

Thanks for reporting this. It's an issue with the example. I shall update the example to reflect both 1.8 and 1.9. Ruby 1.9 doesn't complain when you send multiple block variables to a block when you're only accepting a single argument at the other end, 1.8 however does.

The example should read:

opts = Slop.new do
  command :foo do
    on :v, :verbose

    execute { |o, a| p o.verbose? }
  end
end

Where o is the Slop option set, and a is the arguments array.

I'll update the wiki page, thank you!
