* lisp/org-fold-core.el (org-fold-core--keep-overlays): New internal
macro, signaling `org-fold-core-region' to keep overlays in place and
store new overlays for later use in isearch.
(org-fold-core-region): Never remove overlays and store newly created
ones in `org-fold-core--isearch-overlays' when
`org-fold-core--keep-overlays' is non-nil. Remove resolved FIXME.
(org-fold-core--isearch-setup): Advice `isearch-clean-overlays' as
more reliable way to clear all the temporary overlays created for
isearch. `query-replace' and EVIL packages use
`isearch-filter-predicate' separately as thus `isearch-mode-end-hook'
is not sufficient to ensure that isearch overlays are converted back
to text properties.
(org-fold-core--isearch-show-temporary): Do not alter match data, as
isearch expects the match data to stay unchanged. Arrange the
overlays to be kept for isearch consumption (otherwise, isearch will
signal an error; see
https://list.orgmode.org/orgmode/87pmc4smdg.fsf@fastmail.fm/).
(org-fold-core--create-isearch-overlays): Call `org-fold-core-region'
with let-bound `org-fold-core-style' instead of repeating the code
from `org-fold-core-region'.

* lisp/org-fold-core.el (org-fold-core--isearch-show): Make sure that
the actual isearch match is revealed. This relies on undocumented
behavior of isearch that point is at the match when
'isearch-open-invisible is called.
(org-fold-core-region): Disable 'isearch-open-invisible-temporary
features when `org-fold-core-style' is 'overlays. This is to work
around the undocumented requirement of isearch to _not_ delete the
overlay passed to 'isearch-open-invisible-temporary function. Since
`org-fold-show-set-visibility' may destroy overlays arbitrarily, we
cannot currently support isearch `org-fold-show-context-detail' in
full.

folding state in indirect buffers when 'ignore-indirect is requested
in `org-fold-core--optimise-for-huge-buffers'.
* 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

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.
