This new style for 'whitespace-style' displays the page
delimiter characters "^L" as pretty horizontal lines. (Bug#77544)
This also add a new minor mode to toggle these visualization.
* lisp/whitespace.el (whitespace-style): Add page-delimiters
option.
(whitespace-page-delimiter): New face.
(whitespace--page-delimiters-keyword): New variable.
(whitespace-page-delimiters-mode): New minor mode.
(whitespace-style-face-p, whitespace-color-on): Rework for
display the page-delimiters.
* lisp/whitespace.el (whitespace-display-char-on): Copy from
'standard-display-table' if 'buffer-display-table' is nil. This
avoids overwriting display-table customizations by features that
modify 'standard-display-table' for global effects. (Bug#78522)

regression test.
* lisp/whitespace.el (whitespace--clone): New hook function that is
run after cloning a buffer that copies `whitespace-bob-marker' and
`whitespace-eob-marker' and changes the copies to point to the new
buffer (Bug#59618).
(whitespace-color-on): Register the hook function.

to prevent Emacs from running modification hooks or considering
the buffer to be modified (Bug#60066).

whitespace-looking-back, whitespace-post-command-hook): Redo the
`empty' line highlighting logic to ensure that a buffer change causes
all affected `empty' lines to become (un)highlighted (bug#37467).
Also, for improved UX, don't highlight BoB empty lines at or below
point (not just when point is at 1), or EoB empty lines at or above
point (not just when point is `eobp').
(whitespace-bob-marker, whitespace-eob-marker): Clarify documentation.

last line trailing whitespace in the BoB empty line match to ensure
that those characters get highlighted.
* lisp/whitespace.el (whitespace-color-on): Convert the indentation
matcher from a static regular expression to a function so that changes
to `indent-tabs-mode' and `tab-width' are picked up the next time
`font-lock-flush' runs.
(whitespace--indentation-matcher): The new function matcher.
(whitespace--variable-watcher): New variable watcher that calls
`font-lock-flush' if `whitespace-mode' is enabled for the buffer.
