| So far, it appears that double quotes work.
\x inside double quotes remains ok if "x" isn't a special character,
but ${PWD} will definitely be expanded at assignment time instead of
"display the prompt" time. Try the double quoted thing and then cd
somewhere else and see how it behaves to check this.
Generally, since inside double quotes \\ means just \, and \$ means $
and so forth, you should _always_ use single quotes unless you want
sloshing and parameter substituion to be interpreted. Safer, more
reliable.
