* lisp/files.el (major-mode-remap-alist): New custom var.
(set-auto-mode--last): New var.
(set-auto-mode-0): Obey `major-mode-remap-alist`.
* doc/emacs/modes.texi (Choosing Modes): Document `major-mode-remap-alist`.
* lisp/progmodes/cperl-mode.el: Recommend the use of
`major-mode-remap-alist` over the crude `defalias` solution.
* lisp/textmodes/tex-mode.el (tex--guess-mode): Simplify.
(tex--redirect-to-submode): Obey `major-mode-remap-alist`.
* lisp/textmodes/tex-mode.el (TeX-mode, plain-TeX-mode, LaTeX-mode):
Only define them as aliases in `lisp/loaddefs.el` so we don't
override AUCTeX's own definitions when we load `tex-mode.el`.
* lisp/progmodes/compile.el (compilation-parse-errors-function): Remove.
(compilation--parse-region): Simplify accordingly.
(compilation--compat-parse-errors): Remove function, not used any more.
(compilation-error-list, compilation-parsing-end)
(compilation-old-error-list): Remove vars, not used any more.

back in Emacs-22).
* lisp/textmodes/tex-mode.el: Remove old code that was needed for
Emacs<24.
* lisp/progmodes/prolog.el (prolog-consult-compile): Remove long-dead code.
(compilation-parse-errors-function): Remove declaration, not used any more.
(prolog-parse-sicstus-compilation-errors): Remove function, not used any more.
* lisp/textmodes/tex-mode.el (doctex-syntax-propertize-rules):
Add support for the new ^^X and consider the first ^ of ^^A to be the
closing char for the previous comment.
(doctex-font-lock-^^A): Simplify accordingly.
* lisp/textmodes/conf-mode.el (conf-mode):
* lisp/textmodes/tex-mode.el (tex--redirect-to-submode): The
previous hack to these redirections would disable all local
variables. Try to work around this a bit more.
* lisp/textmodes/tex-mode.el (tex--prettify-symbols-alist): Remove
prettified version of `\par'. Many fonts don't display anything for
the character it was mapped to (#x2029 PARAGRAPH SEPARATOR), so
enabling prettification makes every `\par' disappear (bug#50073).
* lisp/textmodes/tex-mode.el (tex-validate-buffer):
Set `inhibit-read-only` around all modifications of the
read-protected *Occur* buffer (bug#19326).
Add the `occur-match` property, and adjust the extent of the
`occur-target` property, so that next-error and previous-error work
correctly (bug#39121).
* lisp/textmodes/enriched.el: Use lexical-binding.

can properly unplug.
* lisp/textmodes/reftex-cite.el: Use lexical-binding.
(reftex-create-bibtex-file): Remove unused var `file`.
(reftex--found-list): Declare var.
(reftex-offer-bib-menu): Rename local var to `reftex--found-list`.

(reftex-toggle-auto-view-crossref): Delete XEmacs-only code.
(reftex-start-itimer-once): Delete XEmacs-only function.
* lisp/textmodes/reftex-global.el: Use lexical-binding.

* lisp/textmodes/reftex-index.el: Use lexical-binding.
(mark-active, transient-mark-mode): Delete var declarations.
(reftex-index-mode-map): Remove XEmacs-only code.
Use `mapc` so we can use closures instead of hand-built lambdas.

remove unused prefix arg and mark it as a motion command.
(reftex-index-phrases-font-lock-keywords)
(reftex-index-phrases-font-lock-keywords): Move initialization into
declaration.

* lisp/textmodes/reftex-ref.el: Use lexical-binding.
(reftex-label): Remove always-nil var `text`.
(reftex-refstyle): Declare before first use.
(<toplevel>): Use closures rather than `eval` when building commands from
`reftex-ref-style-alist`.
* lisp/textmodes/reftex-sel.el: Use lexical-binding.
(reftex-select-label-mode-map, reftex-select-bib-mode-map):
Use `mapc` so we can use closures instead of hand-built lambdas.
(reftex-select-label-mode, reftex-select-bib-mode): Remove XEmacs-only code.
(reftex-select-data, reftex-select-prompt, reftex-refstyle):
Move declaration before first use.
(reftex--found-list, reftex--cb-flag, reftex--last-data)
(reftex--call-back, reftex--help-string): Move declaration before use,
and rename by adding `reftext--` prefix. Adjust all uses in this file.
For `reftex--found-list` adjust corresponding uses in `reftex-cite.el`.
(reftex-select-item): Explicitly let-bind them.
Remove XEmacs-only code.

(reftex-region-active-p, reftex-overlay-put, reftex-move-overlay)
(reftex-make-overlay, reftex-get-buffer-visiting, reftex-delete-overlay):
Redefine as obsolete aliases. Replace all callers.
(current-message): Remove XEmacs-only definition.
* lisp/textmodes/remember.el: Use lexical-binding.
* lisp/textmodes/table.el (<toplevel>): Use closures rather than `(lambda)
to build commands.
* lisp/textmodes/texinfmt.el: Use lexical-binding.
(texinfo-example-start): Declare var.
(texinfo-format-region, texinfo-format-buffer-1): Remove unused var
`last-input-buffer`.

(texinfo-format-parse-args): Remove unused var `start`.
(texinfo-multitable-widths): Remove unused var `start-of-templates`.

(texinfo-alias): Remove unused vars `start` and `args`.

symbol rather than an expression returning it.
(texinfo-format-deffn): Remove corresponding `eval`.

(texinfo-format-ifeq): Remove unused var `end`.
* lisp/textmodes/texinfo.el: Use lexical-binding.

(texinfo-multiple-files-update): Remove unused vars `next-node-name`
and `previous-node-name`.
* lisp/textmodes/two-column.el: Use lexical-binding.
* lisp/newcomment.el (comment-region-default-1): Allow commenting
out whitespace-only regions (bug#41793).
* lisp/textmodes/tex-mode.el (latex--comment-region): Use it.
(latex-mode): Set a comment style shim.
* lisp/textmodes/tex-mode.el (tex--quote-spec): New function
(bug#14286).
(tex-format-cmd): Use it.
(tex-compile): Don't quote the file names, because we're using
`file-exists-p' and friends on the results later, and that fails
on systems where everything is quoted, and on file names that need
quoting.
* lisp/progmodes/dcl-mode.el (dcl-mode):
* lisp/progmodes/idlw-complete-structtag.el: Recommend
with-eval-after-load instead of load-hooks.
* lisp/calc/calc-ext.el (calc-ext-load-hook):

* lisp/textmodes/tex-mode.el (tex-mode-load-hook):
* lisp/whitespace.el (whitespace-load-hook): Obsolete for
with-eval-after-load. Note that these variables are never declared,
but the byte-compiler will still warn about them if used.
* lisp/textmodes/tex-mode.el (tex-font-lock-keywords-2): End the
expression before the terminating $ in constructions like $\it
identifiername$
(bug#28277). This avoids italicising the final $ character.
This fixes the final $ of the final test case here:
$foo$
\textit{foo}
{\it foo}
$\mathit{identifiername}$
$\textit{identifiername}$
${\it identifiername}$
$\it identifiername$
* lisp/format-spec.el: Use lexical-binding. Remove dependence on
subr-x.el.

don't bother parsing :space-pad which is redundant and unused.
(format-spec--pad): Remove, replacing with...
(format-spec--do-flags): ...this new helper function which performs
more of format-spec's supported text manipulation.
(format-spec): Autoload. Allow optional argument to take on special
values 'ignore' and 'delete' for more control over what happens when
a replacement for a format specification isn't provided. Bring back
proper support for a precision modifier similar to that of 'format'.
* lisp/battery.el (battery-format): Rewrite in terms of format-spec.
(battery-echo-area-format, battery-mode-line-format): Mention
support of format-spec syntax in docstrings.
* doc/lispref/strings.texi (Custom Format Strings):

autoloaded and simplify its uses where possible.

support.

(format-spec-do-flags-truncate, format-spec-do-flags-pad)
(format-spec-do-flags-chop, format-spec-do-flags-case): New tests.
(tex-verbatim-environments): Add "Verbatim".
(tex--guess-mode): Rename from tex-guess-mode and return the mode
rather than calling it.
(tex-mode): Replace second definition with an advice.
