* lisp/vc/diff-mode.el (project-root): Declare.
(diff-find-matching-buffer): New function.
(diff-mode): Use it.
* doc/emacs/vc1-xtra.texi (Other Working Trees): Document
'C-x v w w' in diff-mode buffers.

REFRESH optional argument.
(vc-default-log-incoming): Pass it.
* lisp/vc/vc-git.el (vc-git-incoming-revision): New REFRESH
optional argument. When nil, use cached info (bug#62940).
* lisp/tab-line.el (tab-line-define-keys): New defcustom.
(tab-line--define-keys, tab-line--undefine-keys):
New functions that explicitly bind commands from
'tab-line-mode-map' to 'ctl-x-map'.
(tab-line-mode-map): Leave this keymap empty by default
to avoid breaking 'ctl-x-map' (bug#79323).
(global-tab-line-mode): Call either 'tab-line--define-keys'
or 'tab-line--undefine-keys'.
* etc/NEWS: Announce 'let-alist' support for indexing.
* test/lisp/emacs-lisp/let-alist-tests.el (let-alist-numbers):
Add a test for 'let-alist's support for indexing.
* doc/lispref/lists.texi (Association Lists): Document indexing
with 'let-alist'. (Bug#66509)
This feature was tweaked and last tested with a 2019 edition of
the 'ccls' LSP. The spec does not clearly specify this number
to be 0-indexed, but it would make sense that it would be so.
So there's not need to 1+ - correct the numbers at all before
using them in substring. This would fix the Haskell server use
of this feature (which is bug#79259)
* lisp/progmodes/eglot.el (eglot--sig-info): Fix likely off-by-1.
Escape literal % characters in Eglot URIs
Otherwise, a literal % in a file-name will be interpreted (by the
language server) as if it were a part of a percent-encoded sequence.
See Bug#78984 for context on why `url-path-allowed-chars' cannot be
changed to escape literal % characters.
* lisp/progmodes/eglot.el (eglot--uri-path-allowed-chars): Escape %,
remove the redundant variable definition.
* test/lisp/progmodes/eglot-tests.el (eglot-test-path-to-uri-escape):
test it.
* src/indent.c (vertical-motion): If iterator is inside an overlay,
reset it to the beginning of line before trying to reach goal
column. This prevents point from being stuck at the beginning
of overlay strings during upward motions.

Command edebug-bounce-to-previous-value uses the previous value
observed while single-stepping or evaluating an expression to
bounce point in the outside current buffer to the buffer
position corresponding to that value.
* lisp/emacs-lisp/edebug.el (edebug-previous-value): Add
variable.
(edebug-compute-previous-result, edebug-eval-expression): Update
it.

the binding of "P" to edebug-view-outside.
(edebug-mode-menus): Add menu entry for the new command.

* 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.

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.
