I don’t think you need both alpha and alnum, do you?.  Anyhow, nice
though rx is, you don’t get something that can be used for interactive
use of query-replace-regexp, since the escaping is for a string, rather
than for text entered in the minibuffer, where you don’t have to
double-escape the backslashes.
