master 99600ee 2/2: Don't bind <mouse-2> and RET in *Help* buffers

[Lars Ingebrigtsen]

branch: master
commit 99600ee7b4f7a6b8ab5a25817de21bfadd31c14c
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Don't bind <mouse-2> and RET in *Help* buffers
    
    * lisp/help-mode.el (help-mode-map): Remove key bindings for RET
    and <mouse-2> (bug#49784).
    (help-xref-stack, help-xref-forward-stack, help-xref-stack-item)
    (help-make-xrefs): Fix doc strings -- these aren't used by
    `help-follow', but by `help-follow-symbol'.
    (help-follow-mouse, help-follow): Make obsolete.
