Yes, single quotes is probably better, otherwise you have to escape the $ in ${PWD} for this to have the desired effect.
However, the point of the posting was to point out the error I had in not properly encapsulating the ansi code/colors etc with \[...\]
Once I did that, my command line was behaving properly. :-)
