Your code is correct, but I'd rather say that bash2 was buggy or
incomplete and that bash3 fixed its behavior (in a way that is
not backward compatible), but I'm not a bash developer.

Other different behaviors:

pattern='?'
var='A?'
echo ${var//$pattern/B} ${var//"$pattern"/B}

Now more consistent with the ${var%"$pattern"} and compatible
with ksh93 and zsh's (k)sh emulation
