bug#35392: 26.2; (elisp) `Special Properties' cites missing example

[Drew Adams]

The description of `show-help-function' says that Tooltip mode provides
an example.  Where is a user supposed to find this example?  Is she
supposed to look at the code defining `tooltip-mode'?

Also, this text is a bit misleading because it says:

 Tooltip mode (*note (emacs)Tooltips::) provides an example.

That could easily be misread as saying that node `Tooltips' of the Emacs
manual provides the example, instead of (what it does say) that Tooltip
mode provides the example (but how/where?).
