This affects the behaviour of flex completion when there is a default
completion and the user hasn't entered any input pattern to flex-match
against. It is most visible when icomplete-mode or fido-mode are
being used in conjunctio.
When using M-x man, for instance, the default completion is picked
from text around point. Say it is "emacs" (for Emacs's man page). It
will not match the intended completion, "emacs(1)", exactly. If the
user hasn't yet given any input to the completion prompt, that
completion should bubble to top so that
icomplete-force-complete-and-exit will select it, but it didn't.
This new approach uses 'string-prefix-p' instead of 'equal' to find
the default to bubble to the top. This strategy could eventually be
improved, most naturally by flex-matching the default string to all
the candidates and picking the highest scoring one.
Additionally, the new strategy only considers minibuffer-default if
there is no input in the minibuffer, which seems sensible and produces
a small but noticeable speedup.

to checking the file uid, a second test is added: if the file gid is not
greater than backup-by-copying-when-privileged-mismatch,
backup-by-copying-when-mismatch will also be forced on.
* doc/emacs/files.texi, doc/lispref/backups.texi: Updated documentation.
Also fixed a typo in the Emacs reference manual, changing "higher" to
"no greater" so that the limit is no longer documented reversed.
* lisp/progmodes/python.el (python-shell-send-statement): New function.
(python-mode-map): Bind it to key "C-c C-e", and define a python-menu
item for it. (Bug#38426)

New variable.

constant 4096. (Bug#38561)
Use SAFE_ALLOCA to support large buffers for reading process
output.

`universal-argument` works nowadays. Handle `prefix-arg` a bit more
like `command_loop` does.

(mule-cmds--test-universal-coding-system-argument): New test.
* doc/lispref/syntax.texi (Parser State): mention parse-partial-sexp as a
function returning a parser state, and the function to which one supplies a
parser state as an argument for continued parsing.
Refine the documentation of syntax-ppss-context, and correct the text
introducing it and another function.
* src/w32fns.c (setup_w32_kbdhook): Don't initialize
is_debugger_present here...

name of the new thread.

the new thread object.

exits.

extracted from tab-bar--tab-index-recent.

to sort names of tabs by recency for default values of completing-read.
(tab-prefix-map): Bind RET to tab-bar-select-tab-by-name, and 'm' to tab-move.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt):
* doc/lispref/searching.texi (Regexp Functions):
Be more specific about how the KEEP-ORDER argument actually works.
If nil, the regexp guarantees a longest match; this is the behaviour
that many callers implicitly rely on.

indenting `uselib.
(verilog-read-decls): Fix AUTO* to ignore `protected regions.
(verilog-read-auto-template-middle): Fix AUTO_TEMPLATEs with multiple
module templates and at-REGEXPs, msg3183. Reported by Berk Akinci.

I introduced the bug in 2019-07-09T00:50:39Z!eggert@cs.ucla.edu.
* lisp/jsonrpc.el (initialize-instance jsonrpc-process-connection):
Use buffer-disable-undo in stdout and stderr buffers.
* lisp/jsonrpc.el (Version): Bump to 1.0.9
The `not' and `intersection' forms, and `or' inside these forms,
now accept characters and single-character strings as arguments.
Previously, they had to be wrapped in `any' forms.
This does not add expressive power but is a convenience and is easily
understood.
