AFAICT, that key binding has been the same since at least:

    commit 433ae6f6e191af1d1bc67025200ea54a08761e68
    Author: Richard M. Stallman <rms <at> gnu.org>
    Date:   Sun Aug 25 21:47:10 1991 +0000

        Initial revision

Which says:

    (define-key global-map "\C-h" 'help-command)
    (fset 'help-command help-map)
    (define-key help-map "\C-h" 'help-for-help)
