* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
Treat (not VAR) and (null VAR) as (eq VAR nil) when computing the
extent of switch ops.
* lisp/autorevert.el (auto-revert-mode):
* lisp/files.el (revert-buffer): Mention that there is
revert-buffer-with-fine-grain that is better suited for markers
preservation (bug#49661).
* lisp/emacs-lisp/package.el (package-install-from-buffer): Allow
installing files with different line ending conventions (Unix, DOS
and Macos) (bug#48137).
* src/json.c (Fjson_serialize, Fjson_insert)
(Fjson_parse_string, Fjson_parse_buffer, syms_of_json): Signal
`json-unavailable' if jansson isn't available (bug#48228).
* doc/lispref/commands.texi (Quitting): Document `minibuffer-quit'
(Recursive Editing): Document throwing of function values to `exit'.
* doc/lispref/errors.texi (Standard Errors): Document
`minibuffer-quit'
* lisp/minibuffer.el (minibuffer-quit-recursive-edit): New function.
* lisp/simple.el (minibuffer-error-function): Do not abort keyboard
macro execution if is minibuffer-quit is signaled (bug#48603).
* src/data.c (syms_of_data): New error symbol `minibuffer-quit'
* src/keyboard.c (recursive_edit_1): Implement throwing of function
values to `exit`. In that case, the function will be called without
arguments before returning from the command loop.
(cmd_error):
(Fcommand_error_default_function): Do not abort keyboard macro
execution if minibuffer-quit is signaled.
(command_loop_2): New argument HANDLERS.
* src/macros.c (Fexecute_kbd_macro): Use command_loop_2 instead of
command_loop_1.
* src/minibuf.c (Fabort_minibuffers): Use it.
* doc/emacs/search.texi: Document these additions.
* lisp/replace.el:
Add the commands 'kill-matching-lines' and 'copy-matching-lines'.
'kill-matching-lines' is like 'flush-lines', but adds the lines to the
kill ring as a single string, keeping line endings.
'copy-matching-lines' is like 'kill-matching-lines', but only copies
those lines instead of killing them.
* lisp/dnd.el (dnd-open-local-file): Add file to history.
* lisp/files.el (file-name-history--add): New function (bug#12915).
* lisp/startup.el (command-line-1): Add file to history.
* lisp/wdired.el (wdired--before-change-fn):
(wdired--restore-properties): Widen before doing anything so that
we get all the changed bits (bug#49124).
* lisp/help-fns.el (describe-variable): Store the type.
* lisp/help-mode.el (help-view-source): Use the type. This fixes
the problem when looking for a variable defined in a C file.
* src/buffer.c (Fmake_indirect_buffer):
Match base buffer's inhibit-buffer-hooks.
* test/src/buffer-tests.el (buffer-tests-inhibit-buffer-hooks-indirect):
Add a test (bug#49160).
* lisp/textmodes/remember.el (remember-initial-contents)
(remember-before-remember-hook, remember-destroy): Refer to
`remember-buffer'.
* lisp/textmodes/remember.el (remember-buffer): Make into
defcustom (bug#49373).
* lisp/textmodes/remember.el (remember-initial-contents)
(remember-before-remember-hook, remember-destroy): Refer to
`remember-buffer'.
* lisp/textmodes/remember.el (remember-buffer): Make into
defcustom (bug#49373).
* doc/lispref/hooks.texi (Standard Hooks): Ditto.
* src/callint.c (syms_of_callint): Document the actual usage of
`mouse-leave-buffer-hook' (bug#2932).
* lisp/simple.el (separator-line): Tweak definition to not be so
overwhelming.
* lisp/emacs-lisp/shortdoc.el (shortdoc-separator): Removed.
(shortdoc-display-group): Use make-separator-line.
* lisp/help-fns.el (describe-symbol): Use it.
* lisp/help.el (describe-key): Use it.
* lisp/simple.el (separator-line): New face.
(make-separator-line): New function (bug#49630).
* lisp/progmodes/compile.el (compilation-parse-errors):
Don't omit messages from the error count when FILE is a function
rather than a regexp match number.
The internal representation of columns uses half-open intervals but
don't expose that in the test cases, where we want to use the same
numbers as in the compilation messages.
* doc/lispref/variables.texi (File Local Variables): Document it.
* lisp/files.el (ignored-local-variable-values): New user option
(bug#5003).
(hack-local-variables-confirm): Allow ignoring permanently.
(hack-local-variables-filter): Ignore the permanently ignored
variables.
* lisp/shadowfile.el (shadow-make-fullname): HOST can also be a
remote file name. Bug#49596.
* test/lisp/shadowfile-tests.el (auth-source-save-behavior)
(tramp-cache-read-persistent-data, tramp-persistency-file-name):
Set them globally.
(shadow-test06-literal-groups): Extend test.
