commit b76cdd0c1a7978decc0c1044ad23ecc9432c526a
Author: Stefan Kangas <address@hidden>
Commit: Stefan Kangas <address@hidden>
Delete libraries obsolete since 23.1 and 23.2
Emacs 23.2 was released 10 years ago. old-whitespace.el has a
replacement in whitespace.el and is no longer relevant. The other
libraries implement compatibility with Lucid Emacs, a modified version
of Emacs last released in the 1990s.
* lisp/obsolete/ledit.el:
* lisp/obsolete/lmenu.el:
* lisp/obsolete/lucid.el:
* lisp/obsolete/old-whitespace.el: Delete files. These libraries have
been obsolete since Emacs 23.1 or 23.2.
* etc/NEWS: Announce their deletion.
* admin/authors.el (authors-ignored-files)
(authors-fixed-entries, authors-valid-file-names):
* lisp/emulation/viper.el (viper-mode):
* lisp/ffap.el (ffap-menu-ask): Remove references to deleted files.

-;;; Commentary:
-
-;; URL: http://www.dsmit.com/lisp/
-;;
-;; The whitespace library is intended to find and help fix five different types
-;; of whitespace problems that commonly exist in source code.
-;;
-;; 1. Leading space (empty lines at the top of a file).
-;; 2. Trailing space (empty lines at the end of a file).
-;; 3. Indentation space (8 or more spaces at beginning of line, that should be
-;; replaced with TABS).
-;; 4. Spaces followed by a TAB. (Almost always, we never want that).
-;; 5. Spaces or TABS at the end of a line.
-;;
-;; Whitespace errors are reported in a buffer, and on the mode line.
-;;
-;; Mode line will show a W:<x>!<y> to denote a particular type of whitespace,
-;; where `x' and `y' can be one (or more) of:
-;;
-;; e - End-of-Line whitespace.
-;; i - Indentation whitespace.
-;; l - Leading whitespace.
-;; s - Space followed by Tab.
-;; t - Trailing whitespace.
-;;
-;; If any of the whitespace checks is turned off, the mode line will display a
-;; !<y>.
-;;
-;; (since (3) is the most controversial one, here is the rationale: Most
-;; terminal drivers and printer drivers have TAB configured or even
-;; hardcoded to be 8 spaces. (Some of them allow configuration, but almost
-;; always they default to 8.)
-;;
-;; Changing `tab-width' to other than 8 and editing will cause your code to
-;; look different from within Emacs, and say, if you cat it or more it, or
-;; even print it.
-;;
-;; Almost all the popular programming modes let you define an offset (like
-;; c-basic-offset or perl-indent-level) to configure the offset, so you
-;; should never have to set your `tab-width' to be other than 8 in all
-;; these modes. In fact, with an indent level of say, 4, 2 TABS will cause
-;; Emacs to replace your 8 spaces with one \t (try it). If vi users in
-;; your office complain, tell them to use vim, which distinguishes between
-;; tabstop and shiftwidth (vi equivalent of our offsets), and also ask them
-;; to set smarttab.)
-;;
-;; All the above have caused (and will cause) unwanted codeline integration and
-;; merge problems.
-;;
-;; whitespace.el will complain if it detects whitespaces on opening a file, and
-;; warn you on closing a file also (in case you had inserted any
-;; whitespaces during the process of your editing).
-;;
-;; Exported functions:
-;;
-;; `whitespace-buffer' - To check the current buffer for whitespace problems.
-;; `whitespace-cleanup' - To cleanup all whitespaces in the current buffer.
-;; `whitespace-region' - To check between point and mark for whitespace
-;; problems.
-;; `whitespace-cleanup-region' - To cleanup all whitespaces between point
-;; and mark in the current buffer.
