Mattias Engdegård 59e0b82776 Better ad-hoc Emacs release of symbol introduction override
The file etc/symbol-releases.eld now contains explicit version
information for selected symbols that our NEWS* scraper doesn't
resolve correctly.

* etc/NEWS.unknown: Remove this file, replaced with...
* etc/symbol-releases.eld: ...this new file.
* lisp/help-fns.el (help-fns--first-release-override)
(help-fns--mention-first-function-release)
(help-fns--mention-first-variable-release): New.
(help-fns--mention-first-release): Try the override information first
before scraping the NEWS* files.

;; Emacs versions when certain symbols and variables were first introduced,

;; This file is used to explicitly override the heuristic scraping NEWS*
;; files, when that would result in misleading information.
;;
;; It should contain a single list of (VERSION TYPE SYMBOL), where
;; VERSION is the Emacs version when SYMBOL was introduced as a TYPE,
;; TYPE being `fun' or `var'.

;; Since much of early Emacs source history is lost, these versions are
;; conservative estimates: the actual version of first appearance may very
;; well be much earlier.
;; 13.8 may be the earliest surviving version with source code, although
;; damaged. See
