* lisp/org-fold-core.el: Remove the code overriding
`font-lock-default-fontify-region'. Emacs itself is skipping
fontification of invisible text and doing it more efficiently. The
org-fold fontification overrides are redundant, except when some
poorly written third-party code is forcing fontification inside folded
regions. However, Org does not need to entertain poorly written third
party code, especially when the required supporting code is reducing
font-lock performance and is complicating the maintenance.

according to the list returned by `org-fold-core-get-regions'.
(org-fold-core-save-visibility): New macro, equivalent to
`org-fold-save-outline-visibility'.
The Emacs doc string convention is to document values as-is when that
is clear, and surrounded by `single quotes' otherwise. For example, a
doc string "(a b c)" stands for a list of symbols, and the doc string
"`a'" stands for a single symbol. The doc string "\\=`a" is typically
not correct for that single symbol, because that is equivalent to
"(quote a)" and the typical intent is to talk about the symbol, not
about the Lisp quoting construct. One needs "\\=`X" only when talking
about something intended to be equivalent to "(quote X)", as in the
doc string "(provide \\='org-xyz)".
* lisp/org-fold-core.el (org-fold-core--fix-folded-region): Check
fragility in all the indirect buffers.
* lisp/org-fold.el (org-fold--reveal-headline-at-point): New function
revealing heading line or full heading when the heading only contains
blank lines.
(org-fold--reveal-outline-maybe): Check headline at the end of folded
region as well. Use `org-fold-core--fix-folded-region'.
* lisp/org.el (org-insert-heading): Make sure that the newline in
front of heading is revealed.
* lisp/org-fold-core.el (org-fold-core-style): Explain that the new
folding with text properties can be problematic with third-party
packages, not with Org itself.

Remove. This is very too tricky to implement. In particular, when we
use jit-lock, there can be a race between calls to
`org-fold-core-region' and fontification. For example, consider that
one of the functions in the hook folds drawers and everything is
folded initially. Then, if the user requests unfolding headlines,
drawers, and blocks, it happens before jit-lock is ran in invisible
parts of buffer (out of the display). Those parts will be folded
despite user explicitly requested full unfold, which is wrong. Fixing
this behaviour would involve implementing a full-fledged tracker on
top of jit-lock, which is very too complex and will likely introduce
hard-to-debug errors.

* lisp/org-fold-core.el (org-fold-core-fontify-region): Run
`org-fold-core-first-unfold-functions' on all the regions unmarked by
'org-fold-core-fontified property instead of using incorrect

registered as fontified according to the return value of
`font-lock-default-fontify-region'

regions. We cannot just supply correct return value since jit-lock
does not allow piecewise fontification.

(org-buffer-substring-fontified):
(org-looking-at-fontified): Do not rely on jit-lock. Use
`org-fold-core-fontified' text property to determine whether text is
already fontified.
