exception is in block in docs, but not in code

[adsummos]

Added the exception to the block and made StandardError the default. Also, catching Exception by default is not a good idea because it prevents things like ctrl-c

Thanks a lot!

What do you think about b2c859c ?

Without this edge case handling ctrl-chandling is not possible. SignalException(http://blog.nicksieger.com/articles/2006/09/06/rubys-exception-hierarchy) raised while sleeping was trapped otherwise.

retryable(:sleep => 20, :on => [ SignalException ], :tries => 30) do
  puts 'started!'

  puts 'press ctrl-c now'
  sleep 3
end

Does this make sense?
