Attached is a patch with a couple of minor improvements for the shortdoc
feature:
- Links now show help-echo and are activated with the mouse in a similar
way to the rest of the *Help* buttons.
- When a function is marked as :no-manual, instead of showing no link,
we now show a link to open the function's description. That still
provides a bit more information than the shortdoc and may be a better
fallback than showing no link.
Thanks.

Subject: [PATCH] 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.
