S-tab incorrety translated to C-y


Hi all,

local-function-key-map contains this erraneus entry:

 (S-tab .
        [25])

local-function-key-map also contains this correct entry:

 (S-tab .
        [backtab])

Sadly the first one takes precendence.

Effect: S-tab is translated into C-y and calls 'yank'.

Something somewhere adds a bad entry to local-function-key-map. How to find this
bug?

This line in .emacs works around issue:

(define-key local-function-key-map (kbd "<S-tab>") (kbd "<backtab>"))

I suspected it would be in lisp/term and just used "grep" to find this in ns-win.el:
