Description:
Hi,

I have a nice color prompt:
export PS1=$'\\[\017\E[10;0m\E[1;34m\\]\\u@\\h:\\w\\$ \\[\E[0m\\]'
and use UTF-8 locales everywhere.

When the output of a command doesn't end with a newline, I could perfectly
see it in bash 3.0 since the prompt was printed on its right:

egmont@bobek:~$ echo -n foobar
foobaregmont@bobek:~$ 

Is is also okay in bash 3.1 with 8-bit locales or with simple prompts.
However, if both colors are used in the prompt, and an UTF-8 locale is in
effect, the prompt overwrites the output:

egmont@bobek:~$ echo -n foobar
egmont@bobek:~$ ek:~$ 
                ^
                the cursor stands here

(actually that leftover part of the prompt suggest that probably the prompt
is printed twice, first at the right place (after foobar) and then at the
end of the line).
