4.4-rc1: readline wrapping error when prompt wraps around

When $PS1 contains \[ \] and is longer than the line length then
readline miscounts the wrap coloumn.  For example, set PS1 like this:

PS1="\[$(tput bold)\]$(printf '%*s' $(stty size | awk '{print$2}') x)\[$(tput 
sgr0)\] "

This causes readline to wrap the input too early by the amount of hidden
characters inside \[ \].

Andreas.
