Bug #5023: irb does not like window resizes

Target version: 2.0.0
ruby -v: ruby 1.9.3dev (2011-07-10 trunk 32499) [x86_64-linux]


- open irb
- type until line wraps to the next line
- increase the width of the terminal
- notice that the text of in the second line will not come up to the first line.
-> there is no more useful display/navigation in long lines unless window is resized to exactly the same width. :(

My irb uses libreadline. (Readline module is visible and config in ~/.inputrc is applied.)
Other readline applications like bash do not have that problem.
irb in 1.8 works fine, too.
all versions of 1.9 (including head) have the described problem.
(I tested mainly on my ubuntu box.)
