Copyright-paperwork-exempt: yes

* lisp/auth-source.el (auth-source--obfuscate): Avoid leaking the
length of the password by using PKCS#7 padding.

* lisp/auth-source.el (auth-source--obfuscate): Add comments.

* lisp/auth-source.el (auth-source--obfuscate)
(auth-source--deobfuscate): Check that gnutls is really available.

* lisp/auth-source.el (auth-source--deobfuscate): Use more
obfuscated obfuscation (bug#37196).
(auth-source--pad, auth-source--obfuscate)
(auth-source-netrc-normalize): Use it.
(auth-source-netrc-parse): Ditto.

* lisp/auth-source.el (auth-source-netrc-normalize): Obfuscate
passwords stored in the lexical closure (bug#37196).

* doc/lispref/text.texi (Checksum/Hash):
* src/fns.c (Fmd5, Fsecure_hash):
* lisp/subr.el (sha1): Doc fix to recommend against SHA-1 and MD5 for
security-related applications, since they are not collision
resistant.  (Bug#37420)

* doc/lispref/processes.texi (Process Information): Document it.

* lisp/simple.el (list-processes--refresh): Don't wait for contact
information for non-setup processes.

* src/process.c (Fprocess_contact): Take an optional parameter to
avoid blocking (bug#37408).

* lisp/thingatpt.el (number-at-point): Also return common hex
numbers (bug#37458).

* lisp/gnus/message.el (message-make-forward-subject-function): Change
default value to be a list so it's easier for users to add
functions. Change the type so the customize interface allows selecting
multiple provided functions instead of just one (bug#37470).

* lisp/emacs-lisp/package.el (package-archives): Recommend using https
sources where possible.  (Bug#33825)

* lisp/imenu.el (imenu--make-index-alist): Always return the alist
(bug#30449).

Copyright-paperwork-exempt: yes

* doc/misc/tramp.texi (Inline methods) <sshx, plink, plinkx>:
(External methods) <scpx, pscp, psftp>: Mention, that the remote
login shell could be changed.
(Remote shell setup): Remove description of properties
"remote-shell-login" and "remote-shell-args", they don't matter
here.  Changing the default remote shell works only for some
methods.
(Frequently Asked Questions): Refer to alternative approach fixing
zsh problems.

* etc/NEWS: Some Tramp methods allow to change the remote login shell.

* lisp/net/tramp-sh.el (tramp-default-remote-shell): New defconst.
(tramp-methods): Use it.
(tramp-get-sh-extra-args): New defun.
(tramp-open-shell, tramp-maybe-open-connection): Use it.

* lisp/net/tramp.el (tramp-methods): Adapt docstring.

instead of calling select-window (bug#35385).

See bug #36903

* lisp/gnus/gnus-registry.el (gnus-registry-article-marks-to-chars):
  (gnus-registry-article-marks-to-names): In some circumstances it's
  possible for the user's summary line format spec to include
  registry-specific code, while the registry itself isn't actually
  loaded. Make sure the database is actually a hashtable before
  accessing it.

* src/insdel.c (signal_after_change): Save and restore
interval_insert_behind_hooks and
interval_insert_in_front_hooks across calls to various other
hooks, to prevent their clobbering by those other hooks.
(Bug#37455)

* lisp/net/shr.el (svg--wrap-svg): Add the size to the wrapper to
avoid having the SVG images shrink (bug#37159).

* lisp/net/shr.el (svg--wrap-svg): Add the size to the wrapper to
avoid having the SVG images shrink (bug#37159).

* lisp/pcmpl-gnu.el (pcmpl-gnu-makefile-includes): Fix :version.

* lisp/align.el (align-areas): When given a callback function and
JUSTIFY, pick out the correct parameters (bug#30139).  Suggested
by "John Wiegley" <johnw@gnu.org>.

Problem reported by Katsumi Yamaoka (Bug#37456).
* lisp/startup.el (startup--xdg-or-homedot): Also
prefer .emacs.d if a traditional .emacs file exists.

* src/fileio.c (PICKY_EACCES) [!DOS_NT]: Default to false.

Problem reported by Tino Calancha (Bug#37445).
* src/emacs.c (init_cmdargs): Call file-truename only if
needed, i.e., if invocation-directory ends in "/i386/" on
WINDOWSNT.
* src/lread.c (readevalloop): If the sourcename is not
absolute, make it absolute.  There is no need to convert
non-absolute files into truenames, since absolute files are
not converted into truenames.
(init_lread): Do not convert source-directory into a truename
at startup.  There is no need to do so in a dumped Emacs since
an absolute file name suffices.  The source directory might
not even exist any more, or might have been replaced by an
interloper who takes advantage of the truename calculation.
(syms_of_lread): Remove Qfile_truename; no longer needed.

* src/xterm.c (x_create_toolkit_scroll_bar): On Motif
scrollbars, "foreground" has no meaning, while "background"
means the truck and arrow colors, and "trough" means the
background of the entire widget.  This fix hooks up the Emacs
scrollbar "foreground" color to the XmNbackground resource
and the "background" color to XmNtroughColor which is more in
line with how Xaw scrollbars behave.
