changes.
This function is invoked in shell-mode by the user, and is meant to
emulate what M-. does in zsh and bash: it inserts an argument from a
previous command. Neither zsh nor bash treat a trailing & specially:
M-. simply inserts it if it is encountered. Emacs DID have extra
logic to detect and discard trailing &, but this logic was buggy, and
a && anywhere in the sequence would confuse it. This patch simply
removes that logic to fix the bug and to emulate zsh and bash more
closely
* lisp/comint.el (comint-insert-previous-argument): don't detect and
ignore trailing &
(Bug#25271)
* etc/NEWS: Document this.
This function is invoked in shell-mode by the user, and is meant to
emulate what M-. does in zsh and bash: it inserts an argument from a
previous command. Without a prefix argument, it inserts the last arg
from the previous command; with an argument INDEX, it inserts the
INDEX-th argument. bash counts from the start, while zsh counts from
the end. This patch adds a variable
`comint-insert-previous-argument-from-end' that emulates the zsh
behavior if non-nil.
* lisp/comint.el (comint-arguments): can take in negative arguments to count
from the end, same as indexing in python.
(comint-insert-previous-argument): if
comint-insert-previous-argument-from-end is non-nil, INDEX counts
arguments from the end; if nil, from the beginning

Theme settings now generally aren't actually applied until a call to
`enable-theme-, either one made explicitly or implicitly through
`load-theme' with NO-ENABLE nil. This change has the effect of not
applying theme changes just because we load a lisp file containing a
theme specification. The previous behavior is preserved for the
special case of the `user' theme, which is frequently used for
ad-hoc customization.
* lisp/cus-face.el (custom-theme-set-faces): Call
`custom--should-apply-setting' to decide whether to apply
a setting.

which is often useless newadays.

possibility to visit large files literally in response to
question asked by Emacs.
* etc/NEWS: Mention the new possibility to visit large files
literally.
* lisp/files.el (files--ask-user-about-large-file): Use

focus-change events are sometimes supported on TTY frames.

* doc/emacs/custom.texi (Early Init File):
* etc/NEWS: Warn against using early-init.el as a substitute for
.emacs.

functions. Remove references to the now-obsolete focus hooks.

Vunread_switch_frame.
* src/keyboard.c:
(Finternal_handle_focus_in): New function.
(make_lispy_event): Always report focus events to lisp; don't
translate them to switch events sometimes. Lisp can take care of
creating synthetic switch-frame events via
`internal-handle-focus-in'.

just directly report focus changes to lisp.
* src/xterm.c (x_focus_changed): Remove switch-avoidance logic:

argument optional.
(blink-cursor-check): Make sure that the current frame is a
window-system frame before restarting the blink timer. TTY frames
can get focus, but don't need a blink timer because the terminal
will do the blinking.
* lisp/term/xterm.el
(xterm-handle-focus-in,xterm-handle-focus-out): New functions.
(xterm-rxvt-function-map): Recognize focus notification sequences.
(xterm--init-focus-tracking): New function.

That varaiable was an association between symbols and properties,
effecively duplicating symbol's property lists. It is simpler to just
put properties on symbols. Backward compatibility to the old variable
