Previously, 'find' was called for every marked file (for plain
files and directories both). Now 'find' is only called for
directories.
'module-load' most likely doesn't do what users expect. Users should
use 'load' and its wrappers, which do the right thing.
* doc/lispref/loading.texi (Dynamic Modules): Document
disadvantages of 'module-load' and recommend normal 'load' and
its wrappers instead.
* doc/lispref/internals.texi (Module Functions): Recommend
'load' over 'module-load'.
* src/xfns.c (x_get_net_workarea) [!HAVE_GTK3]:
Define in this case too, since x_get_monitor_attributes_fallback
contains a call to it regardless whether HAVE_GTK3 is defined.
* lisp/vc/vc.el (vc--add-line): Create file if it does not exist.

existing buffer to avoid discrepancies with filesytem. (bug#37185)
* lisp/gnus/gnus-art.el (gnus-article-x-face-command): It's seldom
useful to display the face in an external command, so don't ever

This is a useful property when doing further bit-twiddling with the
magnitude array before/after calling extract_big_integer or
make_big_integer. For example, constructing an emacs_limb_t object
using repeated shift-and-add should work as expected, but relies on
the type not having padding bits. Since the C standard already
guarantees that unsigned integers use a pure binary representation,
not having padding bits is enough to guarantee that the type has
unique object representations in the sense of C++’s
std::has_unique_object_representations.
* doc/lispref/internals.texi (Module Values): Document that
emacs_limb_t doesn’t have padding bits.
* src/emacs-module.c: Verify that emacs_limb_t doesn’t have padding
bits.
* src/xdisp.c (extend_face_to_end_of_line): Don't return early
if face attributes beyond background color and box are set,
since that means these attributes need to be extended past the
EOL.
If minibuffer-default coincided with the first of completions, the
empty list would be returned.

Using the 'dedicated' prop for display-buffer--maybe-at-bottom marks the
window of the buffer "*Process List*" as dedicated, so it won't be replaced
by another buffer that might be visited following links to process buffers
from the buffer "*Process List*".
This previous commit targetting this function introduced a bug whereby
the completion table's sorting function wouldn't be called. That is
fixed by this commit, which also simplifies the function further: it
now skips re-sorting the completions completely if there is no
minibuffer input at all (in other words, when flex isn't doing
anything useful).
* lisp/minibuffer.el (completion--flex-adjust-metadata): Simplify.
(gnus-group-change-level, gnus-make-hashtable-from-newsrc-alist):

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.
* lisp/minibuffer.el (completion--flex-adjust-metadata):
Reformulate sorting strategy.
* lisp/term/ns-win.el (ns-insert-working-text):
(ns-delete-working-text): Change how working text is deleted to handle

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.

output.
