bug#73257: 31.0.50; Deleting obsolete libraries in Emacs 31

[Stefan Kangas]

Severity: wishlist

We usually delete libraries obsoleted 10 years ago at the time of a new
Emacs release.  This should mean that anything made obsolete before
24.5, released on 2015-04-10, are candidates for deletion in Emacs 31.

This is the full list of such libraries:

    24.1 lisp/obsolete/pgg-def.el
    24.1 lisp/obsolete/pgg-gpg.el
    24.1 lisp/obsolete/pgg-parse.el
    24.1 lisp/obsolete/pgg-pgp.el
    24.1 lisp/obsolete/pgg-pgp5.el
    24.1 lisp/obsolete/pgg.el
    24.3 lisp/obsolete/bruce.el
    24.4 lisp/obsolete/info-edit.el
    24.4 lisp/obsolete/iswitchb.el
    24.4 lisp/obsolete/longlines.el
    24.4 lisp/obsolete/meese.el
    24.4 lisp/obsolete/otodo-mode.el
    24.4 lisp/obsolete/rcompile.el
    24.4 lisp/obsolete/sup-mouse.el
    24.4 lisp/obsolete/terminal.el
    24.4 lisp/obsolete/yow.el
    24.5 lisp/obsolete/cc-compat.el
    24.5 lisp/obsolete/crisp.el
    24.5 lisp/obsolete/tpu-edt.el
    24.5 lisp/obsolete/tpu-extras.el
    24.5 lisp/obsolete/tpu-mapper.el
    24.5 lisp/obsolete/vi.el
    24.5 lisp/obsolete/vip.el
    24.5 lisp/obsolete/ws-mode.el

1. We cannot yet remove iswitchb.el, as isearchb.el depends on it (see
   Bug#36260).

2. We also cannot remove longlines.el, as so-long.el depends on it, and
   even recommends it in certain cases.

3. ISTR that Eli objected to removing bruce.el in Emacs 30, so I'm
   assuming this objection this still stands.

Are there any other blockers or considerations?

pgg is still being used.  Please don't delete it on impulse.

I'd leave the TPU and Crisp/Brief emulations alone.

FWIW, I uploaded info-edit.el and iswitchb.el to
Emacs Wiki.  There are wiki pages that refer to
them and code on the wiki that uses them.

Dunno whether other 31-removed libraries should
similarly be archived/uploaded.  I'm not familiar
with them.
