bug#37724: HTML Markdown and Emacs Outline Hash Links in DEMO not working

[Kevin J. McCarthy]

The patch I posted in bug#37729 seems to have partly fixed this problem 
too:

                    (not (listp args))

"README.md#why-was-hyperbole-developed" now seems to work.

"man/hyperbole.html#Smart-Keys" opens the man/hyperbole.html file, but 
it isn't rendered so it gives the error:
  hyperbole.html - Section ‘Smart Keys’ not found in the visible buffer portion

I don't know if that is expected behavior or not.
