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.

;;; Commentary:
|
|
|
|
;; This file replaces erc-complete.el. It provides nick completion
|
|
;; for ERC based on pcomplete. If you do not have pcomplete, you may
|
|
;; try to use erc-complete.el.
|
|
;;
|
|
;; To use, (require 'erc-auto) or (require 'erc-pcomplete), then
|
|
;; (erc-pcomplete-mode 1)
|
|
;;
|
|
;; If you want nickname completions ordered such that the most recent
|
|
;; speakers are listed first, set
|
|
;; `erc-pcomplete-order-nickname-completions' to t.
