;;; +finger.el --- Finger bugfix -*- lexical-binding: t; -*-

|
|
;;; Commentary:
|
|
|
|
;; `net-utils' defines `finger', which purportedly consults
|
|
;; `finger-X.500-host-regexps' to determine what hosts to only send a username
|
|
;; to. I've found that that is not the case, and so I've patched it. At some
|
|
;; point I'll submit this to Emacs itself.
|
|
|
|
;;; Code:
|
|
|
|
(require 'net-utils) ; this requires everything else I'll need.
|
|
(require 'seq)

;; One of those great interactive statements that's actually
|

;; longer than the function call! The idea is that if the user
|
|
;; uses a string like "pbreton@cs.umb.edu", we won't ask for the
|
|
;; host name. If we don't see an "@", we'll prompt for the host.
