bug#3864: 23.1.50; docstring url hyperlinks

[Kevin Ryde]

I did a grep for urls in docstrings which might be hyperlinked.
Diff below from the lisp directory.

It'd be tempting to have M-x checkdoc report on this sort of
thing, except it may too often hit sample input etc instead of
actual followable links.
