(Bug#80129)

* lisp/textmodes/text-mode.el (center-line-mode--track-changes):
New local variable for storing the id of the change tracker registered
for the current buffer.
(center-line-mode--track-changes-signal): New function to be called by
the track-changes library whenever there is a change in the current
buffer.
(center-line-mode--track-changes-function): New function called from the
above signal function, iterates over the lines of the modified region,
calling 'center-line' for each non-empty line.
(center-line-mode): New minor mode.
* etc/NEWS: Document the new minor mode.

* lisp/textmodes/ispell.el (ispell-save-corrections-as-abbrevs):
New user option.
(ispell--abbrev-saving-allowed)
(ispell--save-correction-as-abbrev): New variables.
(ispell--maybe-save-correction-abbrev): New function.
(ispell-word, ispell-process-line): Use them to save corrections
as abbrevs when appropriate (bug#79985).
(ispell-command-loop): Add C-u as command character to toggle
abbrev saving for an immediately following replacement command.
(ispell-help): Document C-u binding.

* doc/emacs/fixit.texi (Spelling): Document new feature.

They're always called immediately before a `<` char, in which case
they do the same anyway.  This saves us from having to touch
 `forward-list-function` in addition to `forward-exp-function`.

While at it, change `sgml-tags-invisible` to use `define-minor-mode`.

* lisp/textmodes/sgml-mode.el (sgml-delete-tag)
(sgml-electric-tag-pair-before-change-function): Prefer `forward-sexp`
over `forward-list`.
(sgml-tags-invisible): Define with `define-minor-mode`.  Don't disable
`cursor-sensor-mode` when we don't need it any more, since some other
package may be using it.  Remove redundant binding of `inhibit-read-only`.

(html-ts-mode--show-paren-data): New function to exclude
unbalanced tags when the closing tag is missing.
(html-ts-mode): Set 'show-paren-data-function' to
'html-ts-mode--show-paren-data' (bug#80151).

(sgml-electric-tag-pair-before-change-function):
Let-bind 'forward-list-function' to nil.
(sgml-delete-tag): Let-bind 'forward-sexp-function'
and 'forward-list-function' to nil.
(sgml-tags-invisible): Let-bind 'forward-list-function' to nil.

All this is required to use the default definitions of sexp/list
that significantly differ from treesit definitions (bug#80151).
