Subject: [PATCH] Rewrite hl-line-mode

The fashion of dual global and minor modes, each managing a replica of
state, has long been outmoded by globalized minor modes (nee
easy-mmode-define-global-mode) around the turn of the century.

* lisp/calendar/todo-mode.el (todo-toggle-item-highlighting,
todo-hl-line-range, todo-modes-set-2): Adapt to new
hl-line-highlight-hook.
* lisp/hl-line.el (hl-line-overlay): Rename hl-line--overlay.
(global-hl-line-overlay, global-hl-line-overlays,
global-hl-line-sticky-flag, hl-line-overlay-buffer,
hl-line-range-function): Obsolesce.
(hl-line--overlay): Erstwhile hl-line-overlay.
(hl-line, hl-line-face): Consolidate.
(hl-line-sticky-flag): Say less (Gen Z Hospital).
(hl-line-overlay-priority): Make this a custom.
(hl-line-highlight-hook): Prefer hook over specialized
hl-line-range-function.
(hl-line-mode): Say less (Gen Z Hospital).
(hl-line-make-overlay): Remove
(hl-line-highlight, hl-line-unhighlight): Rewrite.
(hl-line-maybe-unhighlight): Remove.
(hl-line-turn-on): Necessary for globalized minor mode.
(global-hl-line-mode, global-hl-line-highlight,
global-hl-line-highlight-all, global-hl-line-unhighlight,
global-hl-line-maybe-unhighlight, global-hl-line-unhighlight-all):
Prefer globalized minor mode.
(hl-line-move, hl-line-unload-function): Remove.
* test/lisp/calendar/todo-mode-tests.el (todo-test-item-highlighting,
todo-test-done-items-separator06-bol,
todo-test-done-items-separator06-eol,
todo-test-done-items-separator07): Adapt to consolidated face.

 ;;; Commentary:
 
-;; Provides a local minor mode (toggled by M-x hl-line-mode) and
-;; a global minor mode (toggled by M-x global-hl-line-mode) to
-;; highlight, on a suitable terminal, the line on which point is.  The
-;; global mode highlights the current line in the selected window only
-;; (except when the minibuffer window is selected).  This was
-;; implemented to satisfy a request for a feature of Lesser Editors.
-;; The local mode is sticky: it highlights the line about the buffer's
-;; point even if the buffer's window is not selected.  Caveat: the
-;; buffer's point might be different from the point of a non-selected
-;; window.  Set the variable `hl-line-sticky-flag' to nil to make the
-;; local mode behave like the global mode.
-
-;; You probably don't really want to use the global mode; if the
-;; cursor is difficult to spot, try changing its color, relying on
-;; `blink-cursor-mode' or both.  The hookery used might affect
-;; response noticeably on a slow machine.  The local mode may be
-;; useful in non-editing buffers such as Gnus or PCL-CVS though.
-
-;; An overlay is used.  In the non-sticky cases, this overlay is
-;; active only on the selected window.  A hook is added to
-;; `post-command-hook' to activate the overlay and move it to the line
-;; about point.
-
-;; You could make variable `global-hl-line-mode' buffer-local and set
-;; it to nil to avoid highlighting specific buffers, when the global
-;; mode is used.
-
-;; By default the whole line is highlighted.  The range of highlighting
-;; can be changed by defining an appropriate function as the
-;; buffer-local value of `hl-line-range-function'.
