master e62f719 1/2: Minor shortdoc link improvements

[Lars Ingebrigtsen]

branch: master
commit e62f71988f8e75de676ea5e0775c97eab1d8793a
Author: Daniel Martín <mardani29@yahoo.es>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Minor shortdoc link improvements
    
    * lisp/emacs-lisp/shortdoc.el (shortdoc--display-function): Use
    describe-function as a fallback link when a function is not documented
    in any Info manual.  Also make the link respond to mouse-1, like the
    rest of *Help* links, and add a proper help-echo property.
    * lisp/help-fns.el (help-fns--mention-shortdoc-groups): Same link
    improvement as described before, this time for the shortdoc groups
    (bug#45750).
