(CSI-map, SS3-map, GOLD-map, GOLD-CSI-map)

(GOLD-SS3-map): Initialize in declaration.
(tpu-set-mode-line): Don't throw away other minor mode strings when
turning off the mode.
(tpu-set-match, tpu-match-beginning, tpu-check-match)
(tpu-show-match-markers): Use the insertion-type rather than the +1
offset kludge for tpu-match-beginning-mark.
(tpu-edt-mode): Use define-minor-mode.
(minibuffer-local-must-match-map, minibuffer-local-map): Try to avoid
using the escape sequence and use the real key name instead.
(tpu-reset-control-keys): Don't copy a keymap needlessly.
(tpu-arrow-history): Simplify.
(tpu-edt-on): Set control keys after changing the global map.
(tpu-edt-on, tpu-edt-off): Work unconditionally.
