Non-printing characters need to be bracked with \[...\] to inform bash
that they do not display.  Please see the bash documentation in the
section on "PROMPTING".

\[ begin  a sequence of non-printing characters, which could
   be used to embed a terminal  control  sequence  into  the
   prompt
\] end a sequence of non-printing characters

I believe that will fix your problem.

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

Description:
With PS1='\e[32m$\e[m' when typing something at the prompt, then
pressing  the visible cursor is not positioned after the 
prompt ($) 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/
result:

$cd /home/apexo/
 ^ cursor is now here

now typing: echo  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 
-> 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)

Sorry for not reading the documentation ... it just used to work and I didn't 
expect it to break :)

Thanks for clarifying things.

Regards,
Christian
