Fixes: debbugs:19731
* lisp/net/tramp-sh.el (tramp-histfile-override): Add another choice 'unset.
(tramp-open-shell, tramp-maybe-open-connection): Support it.
src/coding.c (raw_text_coding_system_p): New function.
src/keyboard.c (read_decoded_event_from_main_queue): Use it when the
keyboard coding-system is 'raw-text'.
src/coding.h (raw_text_coding_system_p): Add prototype.
* dired.c (read_dirent): Simplify by removing the need for the
DIR_ENTRY argument. All callers changed. This separates the
MS-DOS idiosyncrasies better from the rest of the code.
* lisp/emacs-lisp/cl-generic.el (cl--generic-search-method): Fix regexp.
* lisp/emacs-lisp/eieio-core.el (eieio--check-type): Remove.
Use cl-check-type everywhere instead.
(eieio-class-object): Remove, use find-class instead when needed.
(class-p): Don't inline.
(eieio-object-p): Check more thoroughly, so we don't treat cl-structs,
such as eieio classes, as objects. Don't inline.
(object-p): Mark as obsolete.
(eieio-defclass-autoload, eieio-defclass-internal, eieio-oref)
(eieio--generic-tagcode): Avoid `class-p'.
(eieio-make-class-predicate, eieio-make-child-predicate): New functions.
(eieio-defclass-internal): Use current-load-list rather than
`class-location'.
* lisp/emacs-lisp/eieio-opt.el (eieio-help-class, eieio-help-constructor):
Use find-lisp-object-file-name, help-fns-short-filename and new calling
convention for eieio-class-def.
(eieio-build-class-list): Remove function, unused.
(eieio-method-def): Remove button type, unused.
(eieio-class-def): Inherit from help-function-def.
(eieio--defclass-regexp): New constant.
(find-function-regexp-alist): Use it.
(eieio--specializers-apply-to-class-p): Handle eieio--static as well.
(eieio-help-find-method-definition, eieio-help-find-class-definition):
Remove functions.
* lisp/emacs-lisp/eieio.el (defclass): Use new eieio-make-class-predicate
and eieio-make-child-predicate.
(eieio-class-parents): Use eieio--class-object.
(slot-boundp, find-class, eieio-override-prin1): Avoid class-p.
(slot-exists-p): Use find-class.
* test/automated/eieio-tests.el (eieio-test-23-inheritance-check): Simplify.
Fixes: debbugs:19734
* lisp/emacs-lisp/backquote.el (backquote-delay-process): Don't reuse `s'
since it may be "equivalent" in some sense, yet different.
* test/automated/core-elisp-tests.el (core-elisp-tests-3-backquote): New test.
* outline.el (outline-hide-entry): Rename from `hide-entry'.
(outline-show-entry): rename from `show-entry'
(outline-hide-body): Rename from `hide-body'.
(outline-hide-region-body): Rename from `hide-region-body'.
(outline-show-all): Rename from `show-all'.
(outline-hide-subtree): Rename from `hide-subtree'.
(outline-hide-leaves): Rename from `hide-leaves'.
(outline-show-subtree): Rename from `show-subtree'.
(outline-hide-sublevels): Rename from `hide-sublevels'.
(outline-hide-other): Rename from `hide-other'.
(outline-show-children): Rename from `show-children'.
(outline-show-branches): Rename from `show-branches'.
* lisp/files.el (save-buffers-kill-emacs): If `confirm-kill-emacs' is
set, but user has just been asked whether they really want to kill Emacs
(for example with a ‘Modified buffers exist; exit anyway?’ prompt) , do
not ask them for another confirmation.
src/dired.c (read_dirent): Accept an additional argument
FIRST_ENTRY. If readdir fails with ENOENT or EACCES the first
time it is called, report the error as if it happened in
open_directory.
(directory_files_internal, file_name_completion): Adjust callers
or read_dirent.
Previously, on non-MS-Windows platforms the code treated most
readdir failures as EOF. This was incorrect, e.g., when readdir
fails with errno == EOVERFLOW. Signal an error instead.
* dired.c (read_dirent):
New function, which signals an error when readdir fails.
(directory_files_internal, file_name_completion): Use it.
src/w32uniscribe.c (uniscribe_list, uniscribe_match): Use bool where
appropriate.
src/w32font.c (struct font_callback_data, w32font_list_internal)
(w32font_driver, w32font_match_internal): Use bool where appropriate.
src/w32menu.c (x_activate_menubar, set_frame_menubar)
(w32_dialog_show, initialize_frame_menubar, w32_menu_show)
(is_simple_dialog): Use bool where appropriate.
(calc-convert-units): Check for missing units.
* lisp/calc/calc-ext.el (calc-init-extensions): Autoload
`calc-convert-exact-units' and assign it a keybinding.
* lisp/calc/calc-help (calc-u-prefix-help): Add help for the
"un" keybinding.
