  used instead for this version.  Remove in-line change history; use
  git instead.

More small fixes for image-dired

* lisp/image-dired.el: Fix commentary to refer to correct Emacs manual
node.
(image-dired--with-db-file): Add declare forms.
(image-dired-hidden-p): Rewrite with cl-loop.  It's not necessary to
run through the whole list.

Remove image-dired-kill-buffer-and-window

This breaks window layout, especially when quitting a
image-dired-display-image-mode buffer.
* lisp/image-dired.el (image-dired-thumbnail-mode-map):
(image-dired-display-image-mode-map): Replace in keymap and menu items
bindings to image-dired-kill-buffer-and-window with quit-window.

new minor mode.
(image-dired-minor-mode-map): New keymap assimilated from
image-dired-setup-dired-keybindings.  In the future, the keymap parent

obsolete function alias.
(image-dired-minor-mode): New minor mode, assuming the role of

additional bindflag parameter.
(set_internal): Only call `notify_variable_watchers' if bindflag is not
SET_INTERNAL_THREAD_SWITCH.
* src/eval.c (do_specbind, do_one_unbind): Add bindflag parameter,
passed on to set_internal and set_default_internal.  Adjust callers.
(rebind_for_thread_switch, unbind_for_thread_switch): Pass
SET_INTERNAL_THREAD_SWITCH to do_specbind, do_one_unbind instead of
temporarily adjusting symbol's trapped_write field.

Minor fix for define-derived-mode

* lisp/emacs-lisp/derived.el (define-derived-mode):
Do not let eg eval-defun reset the values of syntax or abbrev tables,
since they might have been defined externally.  (Bug#16160)

* build-aux/git-hooks/pre-commit: Add whitespace comment.

Move backtrace to ELisp using a new mapbacktrace primitive

(subr-test-backtrace-integration-test): New tests.

`mapbacktrace' and missing argument BASE of `backtrace-frame'.

Use C99 syntax for font drivers

Problem reported by Daniel Colascione in:
http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg00515.html
* src/ftcrfont.c (ftcrfont_driver):
* src/ftfont.c (ftfont_driver):
* src/ftxfont.c (ftxfont_driver):
* src/macfont.m (macfont_driver):
* src/nsfont.m (nsfont_driver):
* src/xfont.c (xfont_driver):
* src/xftfont.c (xftfont_driver):
Use C99 syntax, not the old GNU C syntax.

Obsolete gs.el

* lisp/gs.el: Move to lisp/obsolete.  (Bug#1524)
* doc/lispref/display.texi (Image Formats): Remove postscript.
(PostScript Images): Remove section.
* doc/lispref/elisp.texi: Update menu.

Un-revert recent Ffset change

* src/data.c (Ffset): Reinstate the check for "nil".

Minor advice.el fix

* lisp/emacs-lisp/advice.el (ad-preactivate-advice):
Avoid setting the function definition of nil.
This was happening during bootstrap of org-compat.el,
apparently due to eager macro expansion of code behind
a (featurep 'xemacs) test.

Make etags-tests work in out-of-tree builds

* test/lisp/progmodes/etags-tests.el (etags-bug-158)
(etags-bug-23164): Make them work in an out-of-tree build.
Reported by Ken Brown <kbrown@cornell.edu>.

Avoid crashing if a new thread is signaled right away

* src/thread.c (post_acquire_global_lock): Don't raise the pending
signal if the thread's handlers were not yet set up, as that will
cause Emacs to exit with a fatal error.  This can happen if a
thread is signaled as soon as make-thread returns, before the new
thread had an opportunity to acquire the global lock, set up the
handlers, and call the thread function.

* test/src/thread-tests.el (thread-signal-early): New test.

Fix point motion in cloned buffers

* src/thread.c (post_acquire_global_lock): Call
set_buffer_internal_2 instead of tricking set_buffer_internal_1
into resetting the current buffer even if it didn't change.  This
avoids bug#25165, caused by failing to record the modified values
of point and mark, because current_buffer was set to NULL.  Also,
don't bother re-setting the buffer if there was no thread switch,
as that just wastes cycles.
* src/buffer.c (set_buffer_internal_2): New function, with most of
the body of set_buffer_internal_1, but without the test for B
being identical to the current buffer.
(set_buffer_internal_1): Call set_buffer_internal_2 if B is not
identical to the current buffer.
* src/buffer.h (set_buffer_internal_2): Add prototype.

* test/src/thread-tests.el (thread-sticky-point): New test.

(tramp-test34-utf8-with-ls): Use it.

Strengthen conditions for resizing sibling windows (Bug#25169)

* lisp/window.el (window-resize, delete-window): Resize other siblings
only if `window-combination-resize' equals t (Bug#25169).

Quote filenames containing '~' in prompts

When in a directory named '~', the default value given by
`read-file-name' should be quoted by prepending '/:', in order to
prevent it from being interpreted as referring to the $HOME
directory (Bug#16984).

* lisp/minibuffer.el (minibuffer-maybe-quote-filename): New function.
(completion--sifn-requote, read-file-name-default): Use it instead of
`minibuffer--double-dollars'.
* test/lisp/files-tests.el (files-test-read-file-in-~): Test it.

Undo part of last change

* src/thread.h:
* src/keyboard.c:

* src/w32select.c: Don't include keyboard.h.

* test/src/thread-tests.el (thread-errors): New test.

Clean up compile-tests.el

Switch to lexical binding.  Make checkdoc happy.

* test/lisp/progmodes/compile-tests.el (compile--test-error-line)
(compile-test-error-regexps): Instead of checking a single Boolean
value, use `should' for each attribute of the message to be compared.
(compile-tests--test-regexps-data): Document sixth list element
TYPE.

* src/eval.c (do_specbind): Don't require a "symbol" that is
actually a cons cell, in order to call set-default, as there are

Fix bad quoting of python-shell-interpreter

`python-shell-calculate-command' was using `shell-quote-argument' as if
it was generating a shell command, but its callers don't pass the result
to a shell, and they expect to parse it with `split-string-and-unquote'.
This caused problems depending on the flavor of shell quoting in
effect (Bug#25025).

* lisp/progmodes/python.el (python-shell-calculate-command): Use
`combine-and-quote-strings' to quote the interpreter, so that it can be
parsed by `python-shell-make-comint' successfully using
`split-string-and-unquote'.

* src/lisp.h (struct terminal): Remove unnecessary forward decl.

Make read1 more reentrant

This is needed if ‘read’ is called soon after startup, before the
Unicode tables have been set up, and it reads a \N escape and
needs to look up a value the Unicode tables, a lookup that in turn
calls read1 recursively.  Although this change doesn’t make ‘read’
fully reentrant, it’s good enough to handle this case.
* src/lread.c (read_buffer_size, read_buffer): Remove static vars.
(grow_read_buffer): Revamp to use locals, not statics, and to
record memory allocation un the specpdl.  All callers changed.
(read1): Start with a stack-based buffer, and use the heap
only if the stack buffer is too small.  Use unbind_to to
free any heap buffer allocated.  Use bool for boolean.
Redo symbol loop so that only one call to grow_read_buffer
is needed.
(init_obarray): Remove no-longer-needed initialization.

Fix compilation warnings

* src/thread.c (Fmake_thread): Call emacs_abort, to avoid
compilation warning.

Fix unlikely substitute-command-keys memory leak
