Another bash-3.2 regression: coloured prompt confuses Ctrl+R.

[Volkov Peter]

Hello.

The issue was reported at http://bugs.gentoo.org/156292 and is still
reproducible in bash-3.2 patch level 10 and with redisplay-cursor-patch.

To save you time steps to reproduce the problem:
1. Set PS1='\[\033[01;31m\]\h\[\033[01;34m\] \W \$\[\033[00m\] '
2. cd /usr/share
3. press <ctrl>+R, then press letter 'e' and press <Home> button.

Cursor appears at the first position in the line (the most left column).

This is reported to work as it should in bash-3.1 patch level 17.
