Bash Version: 3.2
Patch Level: 17
Release Status: release

Description:
        With PS1='\e[32m$\e[m' when typing something at the prompt, then
        pressing <Home> the visible cursor is not positioned after the 
        prompt ($) but behind the 8th typed character, the real cursor
        is on the correct position, so when editing visible and real
        command lines differ.

        Example:

        at the given prompt type e.g.: cd /home/apexo/<Home>
        result:

        $cd /home/apexo/
                 ^ cursor is now here
        
        now typing: echo <Return> yields:
        echoes "cd /home/apexo/"

        I encountered this problem on the first 3.2 version I tested (which is 
quite
        some time ago now ... 3.1 doesn't has this bug)
          

Repeat-By:
        PS1='\e[32m$\e[m'
        type at least 11 characters
        press <Home>
        -> cursor is not where it is supposed to be, editing/deleting
        characters now messes up the displayed command line (i.e. it
        doesn't reflect what's in the buffer)
