`cl-defstruct` also defines a type and is also in CL, so
"cl-type" is not precise enough to talk about those types
defined with `cl-deftype`.  Use the term "derived type" to be
more clear, as is done in the HyperSpec.

* doc/misc/cl.texi (Derived types): Move `cl-deftype` to this
new subsection.  Document the use of derived types as method specializers.

* lisp/emacs-lisp/cl-extra.el (cl--types-of-memo): Rename from
`cl--type-unique`.
(cl--derived-type-dispatch-list): Rename from `cl--type-dispatch-list`.
(cl--derived-type-generalizer): Rename from `cl--type-generalizer`.
(cl--derived-type-generalizers): Rename from `cl--type-generalizers`.

* lisp/emacs-lisp/cl-lib.el (cl-generic-generalizers) <derived-types>:
Rename from <cl-types-of>.  Catch but don't hide errors when a derived
type cannot be used as an atomic type specifier.

* lisp/emacs-lisp/cl-preloaded.el (cl--derived-type-list): Rename from
`cl--type-list`.
(cl-derived-type-class): Rename from `cl-type-class`.
(cl--derived-type-class-make): Rename from `cl--type-class-make`.
(cl--define-derived-type): Rename from `cl--type-deftype`.

Rework.  Move to separate section.

separate section.
(flymake--eol-draw-fancy-1, flymake--eol-draw-fancy): New helpers.
(flymake-end-of-line-diagnostics-face): Remove box.

By default, `face-set-spec' sets the override face spec, so face
attributes are combined with defaults rather than replacing them.
This was a behavior change that was an apparently unintended
consequence of commit 6b344a9.

Also set the `face-modified' property, which causes Customize to
flag the face as changed outside Customize.

* doc/misc/use-package.texi (Faces): Document the behavior.
* lisp/use-package/use-package-core.el (use-package-handler/:custom-face):

Various problems were addressed:

- Unbreak Flymake for Emacs 26.3.  Due to use of some Elisp constructs,
  the change completely broke compatibility to Emacs < 29.1.  That
  violated Flymake's status as a :core package as highlighted in its
  description, which has implications for packages depending on it (such
  as Eglot);

- No new two commands are needed (they weren't documented in the manual
  anyway).  The new functionality was integrated in the existing
  flymake-show-buffer-diagnostics;

- Some helper functions aren't needed at all (they weren't marked
  internal anyway);

- The new hook called only when a particular function is called
  non-interactively in a particular way is not useful.  A case for the
  usefulness (if any) of this hook must be made separately.  Such a hook
  should be documented in the manual;

- Added missing recentering after revealing diagnostic in buffer;

- The menu entry "List all problems" was never intended to direct the
  user the user to any particular problem at point;

- The useful new functionality is called out in the manual and NEWS.
