Thanks Ralf, very helpful. Here's what I came up with, which seems to
work:

(setq reftex-format-cite-function 
      '(lambda (key fmt)
         (let ((cite (replace-regexp-in-string "%l" key fmt)))
           (if (or (= ?~ (string-to-char fmt))
                   (member (preceding-char) '(?\ ?\t ?\n ?~)))
               cite
             (concat "~" cite)))))

 
Regards,

Jim
