those aren't recognized by xterm (see manpage)

this is recognized by urxvt (manpage):

       deletekey: string
           The  string  to send when the delete key (not the keypad delete =
key)
           is pressed.  If  unset  it  will  send  the  sequence  tradition=
ally
           associated with the Execute key.
