I thought that Help buffers relied on Font Lock Mode because -- in a
Help buffer -- `C-h v font-lock-mode RET' replied:
Its value is t
Local in buffer *Help*; global value is nil
Non-nil if Font-Lock mode is enabled.
Had the value of `font-lock-mode' been `nil', I would have thought
otherwise.
OTOH the code could be easily rewritten to use font-lock-mode and
propertize via the font-lock-face text property.
Now that I have understood how things work, I doubt that it would be
beneficial to use Font Lock Mode in Help buffers, because the text could
be mixed (for example: Emacs Lisp code and regular text). Therefore, it
makes sense to highlight each portion of text in an specific way, as
Emacs does now.
