* lisp/emacs-lisp/nadvice.el (advice--make-docstring): Make the
bit about the function/macro having an advice into a complete
sentence (bug#31063) and make it less dramatic.
* lisp/emacs-lisp/ert.el (ert-summarize-tests-batch-and-exit):
Always include the number of failed tests, because absence of the
text is not reassuring (bug#36616).
* lisp/emacs-lisp/checkdoc.el (checkdoc--next-docstring): Don't
bug out on malformed Emacs Lisp (bug#34760).
(checkdoc-file-comments-engine): Don't bug out on empty buffers.
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-use-jump-table): Set
to nil. We can turn this back on again when Bug#36447 is solved and
we handle dumped hash tables correctly.
Use a more precise test to determine whether the input to `regexp-opt'
is safe to optimise when KEEP-ORDER is non-nil, permitting more inputs
to be optimised than before. For example, ("good" "goal" "go") is now
accepted.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt):
More precise test for whether the list is safe w.r.t. KEEP-ORDER.
(regexp-opt--contains-prefix): Remove.
* test/lisp/emacs-lisp/regexp-opt-tests.el: Use lexical-binding.

(regexp-opt-test--permutations, regexp-opt-test--match-all)
(regexp-opt-test--check-perm, regexp-opt-test--explain-perm)
(regexp-opt-keep-order): Test KEEP-ORDER.

Now:
No package specified

of newlines in the regexps.

(reb-restart-font-lock): New function.
* lisp/emacs-lisp/re-builder.el (reb-mode-map): Add divider some
dividers (bug#6347).
* lisp/emacs-lisp/rx.el (rx-regexp, rx-literal): Check the cadr of the
form for stringness, not the form itself.
* test/lisp/emacs-lisp/rx-tests.el (rx-to-string-lisp-forms): New test.
* lisp/emacs-lisp/rx.el (rx-regexp): Allow non-string forms.
(rx-constituents): Add literal constituent, which is like a plain
STRING form, but allows arbitrary lisp expressions.
(rx-literal): New function.
(rx-compile-to-lisp): New variable.
(rx--subforms): New helper function for handling subforms, including
non-constant case.
(rx-group-if, rx-and, rx-or, rx-=, rx->=, rx-repeat, rx-submatch)
(rx-submatch-n, rx-kleene, rx-atomic-p): Use it to handle non-constant
subforms.
(rx): Document new form, wrap non-constant forms with concat call.
* test/lisp/emacs-lisp/rx-tests.el (rx-tests--match): New macro.
(rx-nonstring-expr, rx-nonstring-expr-non-greedy): New tests.
* etc/NEWS: Announce changes.
* doc/emacs/buffers.texi (Several Buffers): Document it.
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-mode-map):
Move widen/narrow to `}' and `{'.
* lisp/emacs-list/package.el
(package--imenu-prev-index-position-function
package--imenu-extract-index-name-function): Add Imenu functions
to package-menu-mode (bug#27134).

keystrokes.
(tabulated-list-widen-current-column): New command.
(tabulated-list-narrow-current-column): Ditto. The code was
written by Boruch Baum and then tweaked by Drew Adams (bug#32106)
before some white-space changes before the commit.

* lisp/emacs-lisp/eieio.el (object-print):
* lisp/emacs-lisp/eieio-base.el (eieio-object-set-name-string):
Move the defgeneric before the defmethod, because that makes more
sense.
* lisp/emacs-lisp/bytecomp.el (byte-compile-initial-macro-environment):
Change with-suppressed-warnings so it also affects the macro-expansion of
the body.
A single `cond' form can how be compiled to any number of switch ops,
optionally interspersed with non-switch conditions.
Previously, switch ops would only be used for whole `cond' forms
containing no other tests.
* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-vars):
Rename from `byte-compile-cond-vars'.
(byte-compile--default-val): Remove.
(byte-compile--cond-switch-prefix):
Replace `byte-compile-cond-jump-table-info'; now also returns
trailing non-switch clauses.
(byte-compile-cond-jump-table): New arguments; no longer compiles
the default case.
(byte-compile-cond): Look for and compile switches at any place in the
list of clauses.
* test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data):
Add test expression.
Allow any mixture of `eq', `eql' and `equal', `memq', `memql' and
`member' in a switch-like `cond' to be compiled into a single switch.
* lisp/emacs-lisp/bytecomp.el (byte-compile--common-test): New.
(byte-compile-cond-jump-table-info): Use most specific common test.
* test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data):
Add test cases for multi-value clause cond forms.
* lisp/emacs-lisp/pcase.el (pcase--u1):
Use the most specific of `memq', `memql' and `member' in or-patterns
with constant cases. This improves performance and may help the byte-code
compiler generate a switch.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-member):
Add mixed-type or-pattern test cases.
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-jump-table-info):
Expand `memq', `memql' and `member' to their corresponding
equality tests.
(byte-compile-cond-jump-table): Cases now have multiple values.
