Make the rx `or' and `seq' forms accept zero arguments to produce a
never-matching regexp and an empty string, respectively.
* lisp/emacs-lisp/rx.el (rx-constituents, rx-or): Permit zero args.
(rx): Amend doc string for `or' and `seq'.
* test/lisp/emacs-lisp/rx-tests.el (rx-or, rx-seq): Test the change.
* etc/NEWS (Changes in Specialized Modes and Packages): Mention the change.
* lisp/cus-edit.el (custom-browse-insert-prefix): Remove XEmacs
compat code and make obsolete.
(custom-group-value-create): Use `insert' directly.
* lisp/emacs-lisp/elint.el (elint-check-conditional-form): Don't
refer to function that doesn't have an if any more.
This is a different fix for bug#34909, which should also fix bug#35739.
Our downloading code used to automatically decode the result according
to the usual heuristics for files. This caused problems when we later
needed to save the data in a file that needed to be byte-for-byte
equal to the original in order to pass the signature verification,
especially because we didn't keep track of which coding-system was
used to decode the data.
(package--unless-error): New macro extracted from
package--with-response-buffer-1, so that we can specify edebug and
indent specs.
(package--with-response-buffer-1): Use it. More importantly, change
code so it runs `body` in a unibyte buffer with undecoded data.
(package--download-one-archive): Don't encode with utf-8 since the data
is not decoded yet.
(describe-package-1): Explicitly decode the readem.txt files here.
* lisp/url/url-handlers.el (url-insert-file-contents): Use it.
(url-insert): Don't decode if buffer is unibyte.
* lisp/url/url-http.el (url-http--insert-file-helper): New function,
extracted from url-insert-file-contents.
The previous code had 2 problems:
- It converted `setq` to `setf` in unrelated cases such as
(cl-symbol-macrolet ((x 1)) (setq (car foo) bar))
- It macroexpanded places before `setf` had a chance to see if they
have a gv-expander.
(syntax-ppss-after-change-function): Mark it as obsolete.
* lisp/font-lock.el (font-lock-apply-syntactic-highlight):
Use syntax-ppss-flush-cache instead.
* lisp/emacs-lisp/eieio-base.el (clone): Unbound slots of
eieio-instance-inheritor objects as documented in the docs string
and implemented in the original eieio implementation.
0e8d452 ; * doc/lispref/nonascii.texi (Coding System Basics): Fix gra...
25a2ff7 ; Add missing space in custom.texi

93912ba Be more careful about indent-sexp going over eol (Bug#35286)
* lisp/emacs-lisp/lisp-mode.el (indent-sexp): Only go over multiple
sexps if the end of line is within a sexp.
* test/lisp/emacs-lisp/lisp-mode-tests.el
(indent-sexp-stop-before-eol-comment)
(indent-sexp-stop-before-eol-non-lisp): New tests.
See Bug#31676.
* lisp/emacs-lisp/byte-run.el
(byte-run--unescaped-character-literals-warning): New defun.
* src/lread.c (load_warn_unescaped_character_literals): Use new defun.
(syms_of_lread): Define symbol for new defun.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Use new
defun.
* test/src/lread-tests.el (lread-tests--unescaped-char-literals):
test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--unescaped-char-literals): Adapt unit tests.
* lisp/emacs-lisp/bytecomp.el (byte-compile-setq-default): Delete.
(byte-compile-set-default): Inline the part that it used.
* lisp/emacs-lisp/edebug.el (setq-default): Remove the debug spec.
* src/data.c (Fsetq_default): Delete.
(syms_of_data): Don't register.
* lisp/emacs-lisp/pcase.el (pcase--u1):
Use memql instead of memq to work with bignums (Bug#34781).
* test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-member): Test the above.
* lisp/emacs-lisp/map.el (map-not-inplace): Fix the message of the
error.
(map-put!): When signaling map-no-inplace error, output the map that
cannot be updated inplace.
* lisp/emacs-lisp/seq.el (seq-contains-p): New predicate function. It
is a replacement for seq-contains which cannot be used as a predicate
when a sequence contains nil values as it returns the element found.
(seq-contains): Make obsolete.
* test/lisp/emacs-lisp/seq-tests.el (test-seq-contains-p):
(test-seq-intersection-with-nil, test-seq-set-equal-p-with-nil,
test-difference-with-nil): Add regression tests.
* doc/lispref/sequences.texi (Sequence Functions): Document
seq-contains-p.
(any "a-Z0-9") generated "[0-9]", and (any (?9 . ?0)) generated "[9-0]".
Reversed ranges are either mistakes or abuse. Neither should be allowed.
etc/NEWS: Explain the change.
lisp/emacs-lisp/rx.el (rx): Document.
(rx-check-any-string, rx-check-any): Add error checks for reversed ranges.
test/lisp/emacs-lisp/rx-tests.el (rx-char-any-range-bad): New test.

Make sure archive contents are written using UTF-8 encoding.
(Bug#34909)
(list-packages): Set buffer's encoding to UTF-8.
This allows the user to customize the sorting indicators displayed
near the current column.
* lisp/emacs-lisp/tabulated-list.el (tabulated-list): New group.
(tabulated-list-gui-sort-indicator-asc)
(tabulated-list-gui-sort-indicator-desc)

for new options.
