This also includes changes to if-let and when-let. The single tuple
special case is ambiguous, and binding a symbol to nil is not as
useful as binding it to its value outside the lexical scope of the
binding. (Bug#28254)
* etc/NEWS: Mention.
* lisp/emacs-lisp/subr-x.el (internal--listify):
(internal--build-binding-value-form): Extend to account for
solitary symbols and (EXPR) items in binding varlist.
(if-let*, when-let*): Nix single tuple case and incumbent
bind-symbol-to-nil behavior.
(and-let*): New macro.
(if-let, when-let): Mark obsolete. Redefine in terms of if-let*, so
they implicitly gain the new features without breaking existing code.
* test/lisp/emacs-lisp/subr-x-tests.el: Adjust tests for: lack of
single-tuple special case, lack of binding solitary symbols to nil,
and the introduction of uninterned symbols for (EXPR) bindings. Add
SRFI-2 test suite adapted to Elisp.
* lisp/progmodes/cc-engine.el (c-restore-<>-properties): After failing an
attempted match from the start of a token (in particular, "<<"), move to the
next token rather than the nex character before searching for the next "<".
The security patches released for Emacs 25.3 were less drastic
than what we had immediately put into master. Adjust master to
match 25.3 (Bug#28350).
* lisp/textmodes/enriched.el (enriched-translations):
Re-enable FUNCTION and display translations that are safe.
(enriched-handle-display-prop): Bring back.
(enriched-decode-display-prop): Bring back, but disable
the unsafe part.
This printing, while succint, is rather opaque. At least give an
immediate clue of whether different byte code printouts are for the
same or different byte code objects.
* lisp/emacs-lisp/cl-print.el (cl-print-object): Add object sxhash to
printed token "#<bytecode>".
* etc/NEWS: Mention this.
* lisp/thumbs.el (thumbs-rename-images): Treat the destination
as special only if it is a directory name. When there is
a marked list, turn the destination into a directory name
if it is not already.
Change write-file to be consistent with the new behavior
of copy-file, etc.
* etc/NEWS: Mention this.
* lisp/files.el (write-file): Treat the destination as special
only if it is a directory name.
Do the special dance with the destination only if it is a
directory name, for consistency with copy-file etc. (Bug#27986).
* doc/emacs/files.texi (Copying and Naming):
* doc/lispref/files.texi (Create/Delete Dirs):
* etc/NEWS: Document this.
* lisp/files.el (copy-directory): Treat NEWNAME as special
only if it is a directory name.
* lisp/files.el (files--ensure-directory): New function.
(make-directory): Use it to avoid bugs when (make-directory FOO t)
is invoked on a non-directory, or on a directory hierarchy that
is being built by some other process while Emacs is running.
* test/lisp/files-tests.el (files-tests--make-directory): New test.
* lisp/xdg.el (xdg-desktop-read-group): Add condition to catch
localized strings.
* test/lisp/xdg-tests.el (xdg-desktop-parsing): Add test to ensure
parsing l10n strings doesn't error but is essentially a no-op.
* lisp/gnus/mm-view.el (mm-inline-text):
Do not worry about enriched or richtext type.
* lisp/textmodes/enriched.el (enriched-translations):
Remove translations for FUNCTION, display (Bug#28350).
(enriched-handle-display-prop, enriched-decode-display-prop): Remove.
Use that to extend xdg-desktop-read-file. Also fix a bug where all
entries in all groups were read and returned by xdg-desktop-read-file.
* lisp/xdg.el (xdg-desktop-read-group): New function.
(xdg-desktop-read-file): Use it.
* test/data/xdg/malformed.desktop: New file.
* test/data/xdg/test.desktop: Add another section.
* test/lisp/xdg-tests.el (xdg-desktop-parsing): Test presence of a key
in another group. Test reading a prescribed group. Test detecting a
malformed key=value.
Construct Tramp syntax strings and regular expressions once instead
of every time they are used, and store them in alists keyed by Tramp
syntax.
* tramp.el (tramp-build-remote-file-name-spec-regexp)
(tramp-build-file-name-structure): New functions.
(tramp-prefix-format-alist, tramp-prefix-regexp-alist)
(tramp-method-regexp-alist)
(tramp-postfix-method-format-alist)
(tramp-postfix-method-regexp-alist)
(tramp-prefix-ipv6-format-alist, tramp-prefix-ipv6-regexp-alist)

(tramp-prefix-format, tramp-prefix-regexp, tramp-method-regexp)
(tramp-postfix-method-format, tramp-postfix-method-regexp)
(tramp-prefix-ipv6-format, tramp-prefix-ipv6-regexp)
(tramp-postfix-ipv6-format, tramp-postfix-ipv6-regexp)
(tramp-postfix-host-format, tramp-postfix-host-regexp)
(tramp-remote-file-name-spec-regexp, tramp-file-name-structure):
Use it.
* lisp/net/rcirc.el (rcirc-markup-urls): Use `make-text-button'
instead of `make-button'; the former is much more efficient in large
buffers, and for the purposes of rcirc, changes no functionality.
* lisp/mail/rmailedit.el (rmail-cease-edit): If no
content-type in edited headers, look for one in original
headers and add it to edited headers. (Bug #26918)
Use a marker to track start of new body, so that
content-transfer-encoding gets applied only to body. (Bug #27353).
Ensure blank line at end of message after encoding, not
before.
* lisp/dired.el (dired-mouse-find-file): Allow callers to
specify functions to visit file/directory.
(dired-mouse-find-file-other-window)

files in another window/frame. (Bug#27435)

verilog-substitute-file-name-path): Support -F in verilog getopt files,
bug1171. Reported by George Cuan.

bug1169. Reported by Hoai Tran.
(verilog-read-auto-template-middle): Fix slow template matching on
AUTOINST. Reported by Jeffrey Huynh.
(verilog-pretty-expr): The extra whitespace addition before "=" operators
is now done only if the whole assignment block contains the 2-character
"<=" operator. Remove the unused argument _myre. Use `unless',
`save-excursion' and `when' functions where possible. Internal variables
refactored for clarity. Follow elisp convention for closing parentheses.
By Kaushal Modi.
(verilog-get-lineup-indent-2): Update docstring. Internal variables
refactored for clarity. Earlier EDPOS argument was expected to be a
marker; it is now renamed to END and is now expected to be a position.
Use `when' instead of `if'. By Kaushal Modi.
(electric-verilog-terminate-line): Remove the unused second argument from
`verilog-pretty-expr' call. By Kaushal Modi.
(verilog-calc-1): Fix indentation of a virtual class definition after a
typedef class, bug1080. By Kaushal Modi.
* lisp/gnus/gnus-sum.el (gnus-summary-jump-to-group): Make sure that
the window to open the group buffer doesn't visit the summary buffer.
This fixes a bug: `gnus-summary-next-article' sometimes causes an error
by trying to select nonexistent summary window.
* lisp/xdg.el: Add support for Desktop Entry Specification.
(xdg--user-dirs-parse-line): Check if file is readable.
(xdg-desktop-group-regexp, xdg-desktop-entry-regexp): New variables.

Make it a user option.
(ert-run-tests-batch): Handle ert-batch-backtrace-right-margin nil.
* lisp/progmodes/sql.el (sql-postgres-list-databases): Handle non-zero
exit statuses from `psql -ltX' more gracefully by returning nil.
* test/lisp/progmodes/sql-tests.el
(sql-tests-postgres-list-databases-error): New test.
* doc/misc/tramp.texi (Traces and Profiles): Mention the
backtrace when tramp-verbose is greater than or equal to 10.

Use `tramp-handle-add-name-to-file'.
* lisp/net/tramp-gvfs.el (tramp-gvfs-file-name-handler-alist): Use
`tramp-handle-add-name-to-file' and `tramp-handle-file-truename'.
* lisp/net/tramp-sh.el (tramp-sh-handle-make-symbolic-link): Improve.
* lisp/net/tramp-smb.el (tramp-smb-errors):
Add "NT_STATUS_CONNECTION_DISCONNECTED" and
"NT_STATUS_OBJECT_PATH_SYNTAX_BAD".

(tramp-smb-handle-make-symbolic-link): Improve.
(tramp-smb-read-file-entry): Handle extended file modes in Samba.
* lisp/net/tramp.el (tramp-handle-add-name-to-file)
(tramp-handle-file-truename): New defuns.
* test/lisp/net/tramp-tests.el (tramp-test21-file-links): Extend test.

Also unroll dispatch into a cond.
* lisp/json.el (json-readtable): Remove.
(json-readtable-dispatch): New macro. Assimilate json-readtable.
(json-read): Use the macro.
Previously, inputting "cats & dogs" would lose dogs because the
ampersand signifies a query parameter. Instead, hexify each word while
preserving quotes with split-string.
* lisp/net/eww.el (eww--dwim-expand-url): Join hexified words together
with + separators, instead of replacing whitespace with +.
* lisp/progmodes/cc-defs.el
