I'm trying to track down a long standing issue with my IRb setup that  
is very annoying.  To test, I've commented out everything in  
my .irbrc file and then loaded IRb with:

   $ irb --readline

Now, these steps show the problem:

1. Type:  "1 < 405"
2. Push the left arrow until your cursor is on the space before the 4  
(5 times)
3. Use a backward delete key to remove the <
4. Push the right arrow to move to the end of the line (5 times)
5. Try to type: "

IRb ignores my typing at this point.  Can anyone else confirm that  
they see this behavior?
