|I'm adding this patch which changes the "!!" double exclamation marks in lib/irb.rb to use single exclamation marks "!", I think using single exclamation marks are more formal for outputs and Ruby itself.

|The patch in question was patched from: http://github.com/ruby/ruby -- Please let me know if you want me to patch from SVN trunk instead.

Although your claim is reasonable, we don't want to introduce any
