Bash Version: 3.2
Patch Level: 33
Release Status: release

Description:

        When your prompt includes invisible characters, going through history
        entries leaves the shell confused. The cursor gets misplaced, junk is
        left on the screen and it also seems to affect line wrapping for really
        long lines or short screen widths.

Repeat-By:
        # Start with PS1='$ ', with no invisible characters
        # and define one that does have
        $ PS1='\e[0;address@hidden \W]$i\[\e[m\]'
        address@hidden ~]
        # Type lots of characters
        address@hidden ~]aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
        # Press Up to go through history
        address@hidden ~]aaaaaaaaPS1='\e[0;address@hidden \W]$i\[\e[m\]'
        # Magic! :-)

Fix:
        I didn't look at the code, but this seems related to the issues in
patches bash32-17 and bash32-27.
