Bash Version: 3.2
Patch Level: 48
Release Status: release

Description:
        Redisplay fails if the prompt wraps around and contains invisible
        characters after the wrap point.

Repeat-By:
        (assuming 80 column display)
        $ 
PS1='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\$\[\033[0m\]
 '
        Cycle back and forth through the history.  Eventually readline
        miscounts the four invisible characters at the end of the prompt.

Andreas.
