* doc/lispref/sequences.texi (seq-setq): Document this macro.
* lisp/emacs-lisp/seq.el (seq-setq): New macro.
* test/lisp/emacs-lisp/seq-tests.el (test-seq-setq):
Test this macro (bug#50053).
* lisp/emacs-lisp/map.el: Bump version to 3.1.
(map--merge): New merging subroutine that uses a hash table in place
of lists, for both efficiency and avoiding ambiguities (bug#49848).
(map-merge): Rewrite in terms of map--merge.
(map-merge-with): Ditto. This ensures that FUNCTION is called
whenever two keys are merged, even if they are not eql (which could
happen until now). It also makes map-merge-with consistent with
map-merge, thus achieving greater overall predictability.
* etc/NEWS: Announce this weakening of guarantees.
* test/lisp/emacs-lisp/map-tests.el (test-map-merge)
(test-map-merge-with): Don't depend on specific orderings. Test
that nil is correctly merged into a plist.
* lisp/international/mule-util.el (filepos-to-bufferpos): Give
better errors on `exact' with unknown line endings, and guess at
Unix if `approximate' (bug#36573).
(bufferpos-to-filepos): Ditto.
* doc/misc/tramp.texi (Remote processes): New subsection "Remote
process connection type".
* lisp/net/tramp-adb.el (tramp-adb-handle-make-process):
Use `tramp-process-connection-type' as default connection type.
Improve check for `:connection-type'.
* lisp/net/tramp-sh.el (tramp-sh-handle-make-process):
Use `tramp-process-connection-type' as default connection type.
Improve check for `:connection-type'. Send "stty -icrnl" when
connection type is a pipe.
* lisp/net/tramp.el (tramp-process-connection-type): Allow all
possible values.
(tramp-handle-make-process): Use `tramp-process-connection-type'
as default connection type. Improve check for `:connection-type'.

* doc/lispref/control.texi (Destructuring with pcase Patterns):
Document this macro.
* lisp/emacs-lisp/pcase.el (pcase-setq): New macro. This macro is
the 'setq' equivalent of 'pcase-let'.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-setq): Test this new
macro. (bug#49809).
* lisp/gnus/nnrss.el (nnrss-get-namespace-prefix): Use the car of
parameter el to match what dom-search expects.
* test/lisp/gnus/nnrss-tests.el (test-nnrss-xml): Adjust to what
xml-parse-region produces (bug#34685).
(cl-generic-generalizers): Remember the specializers that match
a given value.
(cl--generic-eql-generalizer): Adjust accordingly.
* test/lisp/emacs-lisp/cl-generic-tests.el (cl-generic-test-01-eql):
Add corresponding test.
* test/lisp/files-tests.el (files-tests-bug-21454, files-colon-path):
Adapt to change in behavior of 'parse-colon-path'.
* lisp/files.el (parse-colon-path): Don't expand the directory
names: that changes the names in ways this function is not
supposed to. (Bug#49918)
* lisp/progmodes/perl-mode.el: Handle variables first to avoid
conflicting with keywords. This fixes cases like "$package"
(bug#49906).
Copyright-paperwork-exempt: yes
* test/lisp/files-tests.el (files-test-auto-save-name-default)
(files-test-auto-save-name-transform)
(files-test-auto-save-name-unique, files-test-lock-name-default)
(files-test-lock-name-unique): Skip the drive letter in absolute
file names on MS-Windows/MS-DOS when comparing file names against
the expected ones.
(files-tests-file-name-non-special--subprocess): Skip test on
MS-Windows/MS-DOS.
The current method of propagating constants through setq was unsound
because it relied on each setq form only being traversed at most once
during optimisation, which isn't necessarily true in general; it could
be made to miscompile code in rare cases.
Since it was only used in limited circumstances, disabling this
optimisation doesn't cost us much.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Don't update the known value when traversing `setq`.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
Now that ffap-file-finder can be ido-find-file, the
noninteractive portion of find-file-at-point cannot
assume ffap-file-finder always takes an argument
(ido-find-file does not).
* lisp/ffap.el (find-file-at-point): Do not call ffap-file-finder.
* test/lisp/ffap-tests.el (ffap-ido-mode): Test it.
* lisp/emacs-lisp/cl-generic.el (cl-generic-generalizers): Evaluate
forms that are eql specializers. Provide backward compatibility
with a warning.
* test/lisp/emacs-lisp/cl-generic-tests.el: Add a test.
* lisp/emacs-lisp/bindat.el (bindat--type): Adhere to the new rule.

* etc/NEWS: Describe the change.
* lisp/so-long.el: (so-long-statistics-excessive-p): New predicate
function using `buffer-line-statistics'.
(so-long-predicate): Use `so-long-statistics-excessive-p' by default.
* etc/NEWS: Describe changes.
* test/lisp/so-long-tests/so-long-tests-helpers.el:
* test/lisp/so-long-tests/so-long-tests.el: Update tests.
Also improve the existing `so-long-tests-predicate' tests.
The default values support preserving the state of `view-mode' when
switching to (and reverting from) `so-long-mode' (bug#45084).
* lisp/so-long.el (so-long-mode-preserved-variables)
(so-long-mode-preserved-minor-modes): New user options.
(so-long-mode-maintain-preserved-variables)
(so-long-mode-maintain-preserved-minor-modes): New functions.
(so-long-remember-all, so-long-after-change-major-mode)
(so-long-mode-revert): Use them.
* etc/NEWS: Describe changes.
* test/lisp/so-long-tests/so-long-tests-helpers.el:
* test/lisp/so-long-tests/so-long-tests.el: Update tests.
* test/lisp/so-long-tests/so-long-tests.el
(so-long-tests-invisible-buffer-function): Suppress warning about
obsolete function `run-window-configuration-change-hook', as we are
using it intentionally (see the preceding code comments and URL for
details).
(so-long-disable-minor-modes): Don't call the mode function to disable
the mode unless it was actually enabled.
(so-long-restore-minor-modes, so-long-restore-variables): Use the
remembered list values, which might be different to the defaults.
Also comments, and spelling consistency changes for the so-long tests
(a fixup for commit 83bc4ad369 which had only addressed so-long.el,
and not the test files).
* lisp/emacs-lisp/cl-macs.el:
((pcase-defmacro type)): Add 'cl-type' pattern.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-cl-type): Add test.
* doc/lispref/control.texi (pcase Macro): Update manual.
With thanks to Stefan Monnier and Eli Zaretskii for their guidance.
Simplify (let ((X1 E1) ... (Xn En)) Xn)
=> (progn E1 ... En)
and (let* ((X1 E1) ... (Xn En)) Xn)
=> (let* ((X1 E1) ... (Xn-1 En-1)) En)
and similarly the case where the body is a constant, extending a
previous optimisation that only applied to the constant nil.
This reduces the number of bound variables, shortens the code, and
enables further optimisations.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-letX): Rewrite using
`pcase` and add the aforementioned transformations.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test cases.
Reported by Gregor Zattler.
* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
Be more careful in the selection of equality.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
Use the `occur-target` text property to keep track of the extents of
all matches on each line instead of just the start of the first match.
Doing so allows us to highlight all matches when jumping to a matching
line instead of just the first one, and it works in a more principled
way. It also removes compatibility problems that were introduced with
occur-highlight-regexp.
For compatibility with code that populate their own occur-mode
buffers, we still accept `occur-target` properties with a single
marker as value.
* lisp/replace.el (occur-highlight-regexp, occur-highlight-overlay):
Remove.
(occur-highlight-overlays): New.
(occur--targets-start): New.
* lisp/replace.el (occur-after-change-function):
(occur-mode-find-occurrence): Replace with...
(occur-mode--find-occurrences): ...this function that returns the
whole `occur-target` property value.
(occur-mode-goto-occurrence, occur-mode-goto-occurrence-other-window)
(occur-goto-locus-delete-o, occur-mode-display-occurrence)
(occur-engine): Adjust to new property format.
(occur--highlight-occurrence): Replace with...
(occur--highlight-occurrences): ...this function that takes
the `occur-target` property value as argument.
(occur-1): Don't use `occur-highlight-regexp`.
* test/lisp/replace-tests.el (occur-highlight-occurrence):
Adapt to new property format.
* test/lisp/replace-tests.el (replace-tests-with-undo):
When testing the "U" (undo all changes) option, the code will delay
and ding which is obnoxious in an automated test.
Disabling that makes the test quiet and about 150 times faster.
