This fixes bug #51814.
* lisp/follow.el (follow-scroll-down): Do away with the optimization of doing
vertical-motion over only one window. Instead move over all windows, to
checck for being close to point-min, and setting point accordingly.
This fixes bug #51590.
list/follow.el (follow-scroll-down): Incorporate the height of the tab line
into the calculation of the window height.
(follow-calc-win-end): Incorporate the pixel heights of the header line and
the tab line the calculation of the buffer position of the bottom screen line.

Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
This is done by setting cursor-in-non-selected-windows buffer locally.
* lisp/follow.el (follow-hide-ghost-cursors): New customizable option.
(follow-mode): Create and set, or kill buffer-local copy of
cursor-in-non-selected-windows when the mode gets enabled or disabled.
(follow-prev-buffer): New variable.

current buffer changes, to ensure that cursors stay visible in non-selected
follow window groups.
* etc/NEWS: Add an entry for this change.
This fixes bug #32848
* lisp/follow.el (follow-adjust-window): If point ends up in a partially
displayed line in a left hand or middle window, move it one line forward, to
prevent unwanted scrolling should make-cursor-line-fully-visible be non-nil.
Don't merge to master. This fixes bug #32848
* lisp/follow.el (follow-adjust-window): If point ends up in a partially
displayed line in a left hand or middle window, move it one line
forward, to
prevent unwanted scrolling should make-cursor-line-fully-visible be
non-nil.
This fixes bug #32874.
* lisp/follow.el (follow-mode): Put follow-pre-redisplay-function onto
pre-redisplay-function instead of putting follow-post-command-hook onto
post-command-hook. Amend the removal operation analogously.
(follow-pre-redisplay-function): New function.

usage if the supplied docstring doesn't already contain the word "ARG".

(easy-mmode--arg-docstring): New function.
(define-minor-mode): Use them.
Remove argument documentation from all minor modes.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
(isearch-lazy-highlight-update): Check it to decide whether to apply
overlays only on the selected window.
* lisp/follow.el (follow-mode): Set isearch-lazy-highlight to ‘all-windows’.
(Bug#17453, bug#21092)
Also rename the current follow-scroll-up/down functions to

height of the current window.

* doc/lispref/windows.texi (Window Start and End, Textual Scrolling)

together with the six variables indirecting to the pertinent group
functions.
* src/window.c

corresponding ...-group-function is set to a function, and if so execute this
function in place of the normal processing.

If a function on the hook `window-size-change-functions' doesn't
restore the current buffer, functions that save and restore the
current window configuration (like `y-or-no-p') could silently
change the current buffer. When `write-file' asked the user
confirmation to overwrite a file, `y-or-no-p' changed the current
buffer, and the wrong buffer was saved to the file.
* lisp/follow.el (follow-windows-start-end): Call `select-frame'
using the `norecord' parameter.
(follow-window-size-change): Restore current buffer. Call
`select-frame' using the `norecord' parameter. Cleanup.

when EOB was isolated in the last follow window.
