POSIX sucks when shells aren't implementing it correctly. POSIX says that PS1 expansion needs to support at least the bang ('!') expansion and the regular parameter expansion ('$' and '${'), but i found that several kinds of almquist shells don't support that even when they are explicitly POSIX-compliant, dash included.

Bash in --posix mode does that perfectly.
