info.el does not use font-lock, so it just *always* parses the page and adds
the fontification info, except it puts it on font-lock-face, so that the
highlighting is only visible if font-lock-mode is turned on. But the work
is done regardless.
Using font-lock (with jit-lock) would make things faster (because lazier) on
large nodes.
