of the NickServ password from both auth-source and the
erc-nickserv-passwords variable.

erc-nickserv-get-password function to lookup NickServ passwords.
* (erc-nickserv-identify-autodetect, erc-nickserv-identify-on-connect,
erc-nickserv-identify-on-nick-change): Call
erc-nickserv-call-identify-function when
erc-use-auth-source-for-nickserv-password is set.

* lisp/gnus/nnmaildir.el (nnmaildir-request-article): Enable
multipart 8bit-content-transfer-encoded files to be displayed
correctly by reading as `raw-text' instead of having Emacs
(incorrectly) decode the files (bug#44307).
Copyright-paperwork-exempt: yes
* src/pgtkterm.c (pgtk_flash): Change size source.
On X, surface_orig is not an image surface but xlib surface, so I
cannot get its size with cairo_image_surface_get_{width,height}.
In some situations, e.g. when the Lisp machinery isn't available, we
can't quit. Don't check the quit flags in such situations, in case
they contain garbage.
* src/sysdep.c (emacs_open_noquit, emacs_openat_noquit): New variants
of 'emacs_open' and 'emacs_openat' that don't check the quit flags.

* src/pdumper.c (pdumper_load):
* src/w32term.c (w32_initialize):
* src/buffer.c (mmap_init):
* src/callproc.c (emacs_spawn): Use them where we can't quit.
In particular, add a new value to the variable, and fix several bugs apparent
with the implementation up till now.
* doc/emacs/mini.texi (Basic Minibuffer): Add a description of the new
non-nil, non-t value of minibuffer-follows-selected-frame.
* doc/emacs/trouble.texi (Quitting): Add a description of how C-g handles
recursive minibuffers when typed in one which isn't the most nested.
* doc/lispref/minibuf.texi (Intro to Minibuffers): Add an @dfn for "active
minibuffer".
(Minibuffer Commands): Document that exit-minibuffer throws an error when not
invoked from the innermost Minibuffer.
(Recursive Mini): Amend the description of the visibility of outer level
minibuffers.
(Minibuffer Misc): In the description of the minibuffer hooks, replace "the
minibuffer" with "a minibuffer".

description of the new non-nil, non-t value.
* lisp/cus-start.el (top level): make the customize entry for
minibuffer-follows-selected-frame a choice between three entries.
* lisp/minibuffer.el (exit-minibuffer): throw an error when we're not in the
most nested minibuffer.
(top level): Bind C-g to abort-minibuffers in minibuffer-local-map.
* lisp/window.el (window-deletable-p): return the symbol `frame' when (amongst
other things) minibuffer-follows-selected-frame is t.
* src/eval.c (internal_catch): Add a mechanism to (throw 'exit t) repeatedly
when the throw currently being processed doesn't terminate the current
minibuffer.

(minibuf_level): extern declaration moved here from window.h.
* src/minibuf.c (minibuffer_follows_frame, minibuf_stays_put)
(minibuf_moves_frame_when_opened): New and amended functions to query the
value of minibuffer-follows-selected-frame.
(choose_minibuf_frame): check (minibuf > 1) in place of (minibufer > 0) at a
particular place. At another place, check that an alleged frame is so and is
live. Before selecting a non-miniwindow on a different frame, ensure it
really is a different frame.
(move_minibuffer_onto_frame): Stack up all recursive minibuffers on the target
frame. Check the minibuf_window isn't in the old frame before setting that
frame's miniwindow to an inactive minibuffer.
(Finnermost_minibuffer_p, Fabort_minibuffers): New primitives.
(this_minibuffer_depth): New function.
(read_minibuf): Record the calling frame in a variable, and switch back to it
after the recursive edit has terminated normally, using
select-frame-set-input-focus. Stack up all the recursive minibuffers on the
miniwindow where a new minibuffer is being opened. After the recursive edit,
switch the selected window away from the expired minibuffer's window.
(nth_minibuffer): New function.
(minibuffer-follows-selected-frame): Change from a DEFVAR_BOOL to a
DEFVAR_LISP.
* src/window.c (decode_next_window_args): Set *minibuf to w's mini-window's
content when that content is a minibuffer.

doc string once again.
(message-forward-make-body-mime): Remove headers when not
encrypted (bug#45631).
(message-forward-make-body): Pass in correct values.
* doc/misc/gnus.texi (Score Variables): In the example showing how to
use a list of functions for gnus-score-find-score-files-find-function,
return a list of strings from the lambda rather than trying to call
the string as a function (bug#45673).
* lisp/textmodes/fill.el (fill-region-as-paragraph): Try to
improve how line breaks are set on unbreakable text with a fill
prefix area that has spaces within (bug#45720).
* lisp/progmodes/prolog.el (prolog-font-lock-keywords): Work in
all modes derived from prolog-mode (bug#45747).
(mercury-mode): Set up variables based on the Prolog system (bug#45747).
Copyright-paperwork-exempt: yes
* lisp/emacs-lisp/lisp-mode.el (lisp-el-font-lock-keywords-2)
(lisp-cl-font-lock-keywords-2): Allow single-character symbol names.
* lisp/help-mode.el (help-xref-symbol-regexp): Also match symbol
names starting with symbol syntax (bug#6601, bug#24309).
* test/lisp/help-mode-tests.el (help-mode-tests-xref-button): Test
hyperlink creation for function names without symbol syntax.
* lisp/emacs-lisp/shortdoc.el (shortdoc--display-function): Use
describe-function as a fallback link when a function is not documented
in any Info manual. Also make the link respond to mouse-1, like the
rest of *Help* links, and add a proper help-echo property.

improvement as described before, this time for the shortdoc groups
(bug#45750).
* lisp/window.el (window-sizable): Don't try to grow a mini window
when the root window's minimum height is already larger than its
actual height (Bug#45737).
* lisp/term/pgtk-win.el (x-gtk-stock-map): Port from X.
(icon-map-list): Port from X.
(x-gtk-stock-cache): Port from X.
(x-gtk-map-stock): Port from X.
* src/pgtkterm.c (syms_of_pgtkterm): Remove duplicated definition.
We first need to register the received process ID so that
'handle_child_signal' checks it. Otherwise we might never call
'waitpid' for these processes, risking deadlock.
* src/callproc.c (call_process):
* src/process.c (create_process): Don't unblock SIGCHLD before
registering the process ID to wait for.
* src/callproc.c (emacs_spawn): Accept a signal set from the caller.

by Pankaj Jangid.
* lisp/progmodes/flymake.el (flymake--mode-line-counter): Count
diagnostics by severity level, not by type.
(Version): Bump to 1.1.1
Implement a limited form of tail-call optimization for the special
case of recursive functions defined with `cl-labels`. Only self-recursion
is optimized, no attempt is made to handle more complex cases such a mutual
recursion.
The main benefit is to reduce the use of the stack, tho in my limited
tests, this can also improve performance (about half of the way to
a hand-written `while` loop).
(cl--self-tco): New function.
(cl-labels): Use it.
* lisp/subr.el (letrec): Optimize single-binding corner case.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels): Add tests
to check that TCO is working.
