* 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.
(whitespace-color-off): Unregister the hook function.
* test/lisp/whitespace-tests.el
(whitespace-tests--with-test-buffer): New macro.
(whitespace-tests--check-markers): New function.
(whitespace-tests--indirect-clone-breaks-base-markers)
(whitespace-tests--indirect-clone-markers)
(whitespace-tests--regular-clone-markers): New tests.
* lisp/whitespace.el (whitespace--empty-at-bob-matcher)
whitespace--empty-at-eob-matcher, whitespace--update-bob-eob):
Silently add the `font-lock-multiline' text property when
highlighting beginning-of-buffer and end-of-buffer empty lines
to prevent Emacs from running modification hooks or considering
the buffer to be modified (Bug#60066).
* test/lisp/whitespace-tests.el
(whitespace-tests--empty-bob-eob-modified): Add a regression test.
* lisp/whitespace.el (whitespace--empty-at-bob-matcher,
whitespace--empty-at-eob-matcher, whitespace--update-bob-eob,
whitespace-color-off, whitespace-color-on,
whitespace-empty-at-bob-regexp, whitespace-empty-at-eob-regexp,
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.
* test/lisp/whitespace-tests.el (whitespace--with-test-buffer,
whitespace--fu, whitespace-tests--empty-bob,
whitespace-tests--empty-eob): Add tests.
* lisp/whitespace.el (whitespace-empty-at-bob-regexp): Include any
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.
(whitespace--watched-vars): List of variables to watch.
(whitespace-unload-function): Un-watch the variables. (bug#56103).

highlights only the first character over the whitespace-line-column
limit (bug#55980).

Also, fix some awkward wording in doc strings while at that.

regexp, it's a string (that's expanded with format to be a regexp).

is there.

Since 'add-to-list', being a plain function, cannot access lexical
variables, such use must be rewritten for correctness.
(Some instances actually do work thanks to a compiler macro,
but it's not something code should rely on.)
