Cutting and pasting code sections from Mozilla to emacs with the new Auto Code Wrap feature didn't work too well for me at first, so I hadn't been using it. Tonight I investigated further and found that the following line in my .emacs config file fixes it for me. 
;; perlmonks soft-hyphen fix (noop for hidden char)
(global-set-key "\xad" ())

Update: Furthermore, putting this in my ~/.inputrc file fixes it for my shell. 
"\xAD":noop
