Thanks for your quick reply, Kent!  But somehow I don't get it:

  jw@raven> irb
  irb(main):001:0> require 'readline'
  => false
  irb(main):002:0> readline
  asdf^[[D^[[D^[[A^[[A
  => "asdf\e[D\e[D\e[A\e[A\n"

The ^[[D is the result of the up-arrow and ^[[A is the result of the
left-arrow.  "ri readline" mentiones:

     IO::readlines, IO#readline, IO#readlines, Kernel#readlines,
     Kernel#readline, Pathname#readlines, Zlib::GzipReader#readline,
     Zlib::GzipReader#readlines

But none of them seem to support line-editing or history. :-(

Any idea what is going wrong here?
