Colorized output breaks linewrapping with readline

Question

I\'m working with colorizing some output using readline in Ruby, but I am not having any luck getting line wrapping to work properly. For example:

\"\\e[01;

This problem is not ruby-specific - it occurs in bash too. If you put in a bash shell

PS1="\e[01;32mThis prompt is green and bold\e[00m > "

you will see the same result as above. But if you put in

PS1="\[\e[01;32m\]This prompt is green and bold\[\e[00m\] > "

you will get the result you wanted.
