Confirmed the patch broke emacs-22.1-8.fc8.x86_64 (M-x shell ...). readline
checks for custom RL_REDISPLAY_FUNCTION and behaves differently in such case.
Sorry for suggesting RL_REDISPLAY_FUNCTION - I did not verify it more.
Now just to find out how to supply GDB_RL_REDISPLAY simulating the original
behavior.
