Use lexical-binding in all the lisp/obsolete/*.el files. While at it, removed redundant :group arguments and used #' to quote functions. Commented out the key bindings which the #' revealed to lead to non-existing commands, and replaced those revealed to be obsolete. * lisp/obsolete/cl-compat.el: Use cl-lib. * lisp/obsolete/cust-print.el: Assume `defalias` exists. (with-custom-print): Use `declare`. * lisp/obsolete/iswitchb.el (iswitchb-init-XEmacs-trick) (iswitchb-xemacs-backspacekey): Remove functions. * lisp/obsolete/landmark.el (landmark, landmark-nslify-wts): Prefer `apply` to `eval`. * lisp/obsolete/longlines.el (longlines-mode): Don't use `add-to-list` on a hook. * lisp/obsolete/pgg-gpg.el (pgg-gpg-process-region): Use `clear-string`. * lisp/obsolete/pgg-pgp.el (pgg-pgp-encrypt-region): Remove oddly unused var `passphrase`. (pgg-pgp-verify-region): Declare var `jam-zcat-filename-list`. * lisp/obsolete/pgg-pgp5.el (pgg-pgp5-encrypt-region): Remove oddly unused var `passphrase`. (pgg-pgp5-verify-region): Declare var `jam-zcat-filename-list`. * lisp/obsolete/pgg.el: Remove some XEmacs compatibility code. (pgg-run-at-time, pgg-cancel-timer, pgg-clear-string): Remove functions. Use their core equivalent instead. * lisp/obsolete/rcompile.el (remote-compile): Remove unused vars `l`, `l-host`, `l-user`, and `localname`. * lisp/obsolete/starttls.el (starttls-any-program-available): Use `define-obsolete-function-alias`. * lisp/obsolete/tls.el (tls-format-message): Delete function, use `format-message` instead. * lisp/obsolete/url-ns.el (url-ns-prefs): Use `with-current-buffer` and `dlet`. * lisp/obsolete/vip.el (vip-escape-to-emacs): Remove unused var `key`. (vip-command-argument, vip-read-string, ex-delete, ex-line): Remove unused var `conditions`. (ex-map): Use a closure instead of `eval`. (ex-set): Make it an alias of `set-variable`. (ex-substitute): Remove unused var `cont`. * lisp/obsolete/abbrevlist.el: * lisp/obsolete/bruce.el: * lisp/obsolete/cc-compat.el: * lisp/obsolete/cl-compat.el: * lisp/obsolete/cl.el: * lisp/obsolete/complete.el: * lisp/obsolete/crisp.el: * lisp/obsolete/cust-print.el: * lisp/obsolete/erc-compat.el: * lisp/obsolete/erc-hecomplete.el: * lisp/obsolete/eudcb-ph.el: * lisp/obsolete/fast-lock.el: * lisp/obsolete/gs.el: * lisp/obsolete/gulp.el: * lisp/obsolete/html2text.el: * lisp/obsolete/info-edit.el: * lisp/obsolete/iswitchb.el: * lisp/obsolete/landmark.el: * lisp/obsolete/lazy-lock.el: * lisp/obsolete/longlines.el: * lisp/obsolete/mailpost.el: * lisp/obsolete/mantemp.el: * lisp/obsolete/meese.el: * lisp/obsolete/messcompat.el: * lisp/obsolete/metamail.el: * lisp/obsolete/mouse-sel.el: * lisp/obsolete/nnir.el: * lisp/obsolete/old-emacs-lock.el: * lisp/obsolete/otodo-mode.el: * lisp/obsolete/patcomp.el: * lisp/obsolete/pc-mode.el: * lisp/obsolete/pc-select.el: * lisp/obsolete/pgg-def.el: * lisp/obsolete/pgg-gpg.el: * lisp/obsolete/pgg-parse.el: * lisp/obsolete/pgg-pgp.el: * lisp/obsolete/pgg-pgp5.el: * lisp/obsolete/pgg.el: * lisp/obsolete/rcompile.el: * lisp/obsolete/s-region.el: * lisp/obsolete/sb-image.el: * lisp/obsolete/sregex.el: * lisp/obsolete/starttls.el: * lisp/obsolete/sup-mouse.el: * lisp/obsolete/terminal.el: * lisp/obsolete/tls.el: * lisp/obsolete/tpu-edt.el: * lisp/obsolete/tpu-extras.el: * lisp/obsolete/tpu-mapper.el: * lisp/obsolete/url-ns.el: * lisp/obsolete/vc-arch.el: * lisp/obsolete/vi.el: * lisp/obsolete/vip.el: * lisp/obsolete/ws-mode.el: * lisp/obsolete/yow.el: Use lexical-binding.
