Followup: I got it to work by using the onvalidation parameter in the form.accepts() function. When there is a blank password, I insert a temporary, bogus password into form.vars, and then use the onvalidation function to replace that bogus stuff with the previous password, already in encrypted form.
I'd be interested to know if there is an easier/better way to do this.
