tooltip custom group: duplicate labels

[Juri Linkov]

M-x customize-group RET tooltip RET
C-s Use echo area C-s C-s

The tag "Use echo area" is used twice in the same customization buffer.

Its first occurrence comes from emacs/lisp/tooltip.el:

(defcustom tooltip-use-echo-area nil
  "Use the echo area instead of tooltip frames for help and GUD tooltips."
  :type 'boolean
  :tag "Use Echo Area"
  :group 'tooltip)

and the second occurrence comes from emacs/lisp/progmodes/gud.el:

(defcustom gud-tooltip-echo-area nil
  "Use the echo area instead of frames for GUD tooltips."
  :type 'boolean
  :tag "Use echo area"
  :group 'tooltip)

I propose to remove :tag from all GUD tooltip options to reveal their
true identities to the users of Customize.
