IRB history (up arrow key) prepends a few characters to the command

[tconn89]

irb(main):001:0> p "first command"
irb(main):002:0> p "second command"

Now if I press up twice to remember first command, I get this

irb(main):003:0> p "second command" first ______________________________________^ And I can only delete to here I then have to control-C to goto a new empty line

In my .irbrc: require 'fancy_irb' FancyIrb.start({:colorize => {:input_prompt => [:white]}})

I cannot reproduce; it is probably readline-related, though.

Can you please give your: Readline::VERSION
