* lisp/progmodes/lua-ts-mode.el (lua-ts--comment-font-lock):
Apply 'font-lock-comment-delimiter-face' to the entire span of
initial dashes. In particular, this improves the appearance of
LuaCATS and EmmyLua style annotations which use "---".
* test/lisp/progmodes/lua-ts-mode-resources/font-lock.lua:
Add tests. (Bug#79258)
* doc/misc/calc.texi (Customizing Calc): Document the new option.
* etc/NEWS: Document the new option.
* lisp/calc/calc.el (calc-inhibit-startup-message): New option to
inhibit Calc’s startup message.
(calc): Respect the option in Calc’s startup code.
* test/lisp/calc/calc-tests.el (ert): Require ert-x for
'ert-with-message-capture'.
(calc-inhibit-startup-message): Test the new user option.
(markdown-ts--range-settings): Move embed settings
for html/toml/yaml to 'markdown-ts-setup'.
(markdown-ts-setup): Append range rules to 'treesit-range-settings'
only when grammars for html/toml/yaml are installed.
* lisp/org/org-habit.el (org-habit-build-graph): Rewrite without using
string mutation (using vectors instead), fixing a bug where
org-habit-completed-glyph and org-habit-today-glyph wouldn't display
properly if in the U+0080..00FF range, discovered by the more restricted
string mutation.

This fixes a failure in 'test-custom-opts' caused by both strings
and integers being used for 'lua-prefix-key'.
* lisp/progmodes/lua-mode.el (lua-prefix-key): Convert option to
'key-sequence' type.
(lua-mode-map, lua-prefix-key-update-bindings, lua-set-prefix-key)
(lua--customize-set-prefix-key): Adjust to the change of type for
'lua-prefix-key'.
(lua-prefix-mode-map): Use 'defvar-keymap'. (Bug#79335)
* lisp/gnus/nnimap.el (nnimap-open-connection): Use 'tls.
(nnimap-open-connection-1): Check 'tls before 'ssl.
* lisp/mail/smtpmail.el (smtpmail-stream-type): Add 'ssl to
allowed values, state 'tls is preferred.
Rather than using minibuffer-with-setup-hook, just pass the list
of default file names as a regular argument to read-file-name.
This allows read-file-name to run abbreviate-file-name on the
defaults as it normally does, instead of the defaults appearing
in expanded form.
dired-dwim-target-defaults changes slightly to return the
correct default at the start of the list.
* lisp/dired-aux.el (dired-do-create-files)
(dired-compare-directories): Pass default file names as an
argument. (bug#79293)
(dired-dwim-target-defaults): Return the correct default at the
start of the list.
Previously, one could select a completion via M-<up>/M-<down>,
but then RET would not actually select the chosen completion.
With the addition of completion-auto-deselect, this is not
actually necessary: we can reasonably assume that when a
completion is selected, the user wants to use that, since their
last action must have been to select it. So, just choose the
selected completion on RET. This lets us default
minibuffer-completion-auto-choose to nil.
For minibuffers with require-match completion, this can be done
by changing the existing command bound to RET. For minibuffers
with nil require-match completion, RET was previously bound to
exit-minibuffer, and changing exit-minibuffer to have this logic
is risky. We handle that case by adding a new
minibuffer-completion-exit which wraps exit-minibuffer and bind
RET to it.
* lisp/minibuffer.el (minibuffer-insert-completion-if-selected)
(minibuffer-completion-exit, completion--selected-candidate):
Add.
(minibuffer-complete-and-exit): Call
minibuffer-choose-completion. (bug#77253)
(minibuffer-local-completion-map): Bind RET to
minibuffer-completion-exit, overriding exit-minibuffer.
(completion-in-region-mode-map): Bind RET to
minibuffer-choose-completion when there's a selected candidate.
(minibuffer-completion-auto-choose): Default to nil.
(minibuffer-visible-completions--filter)
(minibuffer-visible-completions-map): Delete RET binding, no
longer necessary.
* lisp/simple.el (completion-setup-function): Update completion
help text to show more correct bindings.
* test/lisp/minibuffer-tests.el (completions-header-format-test)
(minibuffer-next-completion): Set
minibuffer-completion-auto-choose=t explicitly.
(with-minibuffer-setup, minibuffer-completion-RET-prefix)
(completion-in-region-next-completion): Add new tests.
* etc/NEWS: Announce.
* lisp/progmodes/lua-mode.el (lua-indent-level): Contemporary Lua
style guides no longer recommend 3 as default. Change type to
'natnum'.
(lua-always-show, lua-get-block-token-info)
(lua--backward-up-list-noerror, lua-make-indentation-info-pair)
(lua-accumulate-indentation-info)
(lua-calculate-indentation-block-modifier): Quote function names.
(lua-toggle-electric-state): Re-format to avoid confusion.
(lua-is-continuing-statement-p-1): Fix typo.
(lua--builtins): Move docstring to correct location.
(lua-is-continuing-statement-p-1): Remove unnecessary 'or'.
(lua-make-lua-string): Remove excessive backslashes and
unnecessary use of a temporary buffer.
(lua-find-matching-token-word): Make it clear that 'goto-char' is
only used only for its side-effect.
* src/xdisp.c (next_element_from_display_vector): Only switch the
iterator from unibyte to multibyte, never in the other direction,
and not if the original character came from a unibyte buffer.
(Bug#79317)
* lisp/erc/erc-fill.el (erc-fill--wrap-measure): Using
`buffer-text-pixel-size' for measuring text size in the selected window
can end up triggering a scroll, which then requires imperfect countering
by the scrolltobottom module, especially with regard to the option
`erc-scrolltobottom-all'. Thanks to Alcor for reporting and helping
with this bug, which was introduced along with fill-wrap in ERC 5.6.
* lisp/progmodes/ruby-mode.el (ruby-flymake-simple): Update
regular expression to handle new versions of Ruby including the
location of the executable in the output.
The following changes make the changes for bug#79275 less
radical, closer to their previous shape, while still fixing
that bug.
* src/xdisp.c (push_prefix_prop, get_it_property): Restore
original code that determined the object and position on it.
(get_line_prefix_it_property): Take FROM_BUFFER from the actual
object of the prefix property.
* lisp/progmodes/bug-reference.el (bug-reference-setup-from-vc-alist):
Add comment explaining the meaning of the nil argument when calling
vc-call-backend. Even though "origin" and nil are equivalent when using
the git backend, it is more intelligible to see "upstream" and "origin"
passed explicitly (bug#79276).
