Move the fitting of a printed representation into a limited number of
characters using appropriate values of print-level and print-length

function.

* lisp/emacs-lisp/debug.el: (debugger-buffer-state): New cl-defstruct.
(debugger--restore-buffer-state): New function.
(debug): Use a debugger-buffer-state object to save and restore buffer
state. Fix bug#15749 by leaving an unused buffer in debugger-mode,

* lib/ieee754.in.h, m4/ieee754-h.m4: New files, from Gnulib.
* src/lisp.h (IEEE_FLOATING_POINT): Now a macro so that it
can be used in #if.
* src/lread.c, src/print.c: Include <ieee754.h> if
IEEE_FLOATING_POINT, not if HAVE_IEEE754_H.
* src/lread.c (string_to_number):
* src/print.c (float_to_string):
Process NaNs only on IEEE hosts, and assume <ieee754.h>
in that case.
Add an Edebug matching function for cl-macrolet which keeps track of
its bindings and treats them as macros without Edebug specs when found
in the body of the expression.
* lisp/emacs-lisp/edebug.el (edebug--cl-macrolet-defs): New variable.
(edebug-list-form-args): Use it.

New test.
* test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el
(edebug-test-code-use-cl-macrolet): New function.
The done items separator is not reachable by todo-mode navigation
commands, but it is e.g. by C-n and C-p. Ensure that invoking
todo-mode commands with point on the separator does not result in
unexpected results, errors or file corruption (bug#32343).
* lisp/calendar/todo-mode.el (todo-insert-item--basic): Make
copying item and inserting item "here" noops when invoked on done
items separator. Consolidate error handling of these cases. Also
restrict "here" insertion to valid positions in the current
category, since this is simpler than the previous behavior of
inserting as the first item, which was moreover undocumented,
counterintuitive and superfluous.
(todo-set-item-priority, todo-move-item, todo-item-done)
(todo-item-start, todo-item-end): Make noops when invoked on done
items separator.
* test/lisp/calendar/todo-mode-tests.el: Require ert-x.
(todo-test--insert-item): Add formal parameters of
todo-insert-item--basic.
(todo-test--done-items-separator): New function.
(todo-test-done-items-separator01-bol)

These should be portable nowadays.
* src/data.c (isnan): Remove.
* src/floatfns.c (isfinite, isnan): Remove.
* src/print.c: Include math.h, for isinf and isnan.
(float_to_string): Simplify by using them.
* nt/inc/ms-w32.h (__POSIX_2008_DEPRECATED)
[__MINGW32_VERSION >= 5001000L]: Define to nothing, to avoid
deprecation warnings about gettimeofday with mingw.org's MinGW
runtime 5.1 and later.
It might be argued that a hidden string is more legible when using
?* as the hidden character instead of ?.
For example, the following strings have the same length:
"......"
"******"
It's slighly easier to visually count the number of characters in the second
string (Bug#32220).
* lisp/subr.el (read-passwd): Prefer ?* as default char instead of ?.
* doc/lispref/minibuf.texi (Reading a Password): Update manual.
; * etc/NEWS (Changes in Emacs 27.1): Announce the change.
* lisp/wdired.el (wdired--restore-dired-filename-prop): If the
file name is a symbolic link, only propertize the link name. This
prevents wdired-create-parentdirs from turning the link into a
directory.
After every change in wdired-mode, put the dired-filename text
property on the file name. This ensures that changing some but not
all characters in the name succeeds with non-nil
wdired-use-interactive-rename (bug#32173) and it also ensures that
changed names can be found (e.g. by dired-isearch-filenames) while
still in wdired-mode.
* lisp/wdired.el (wdired--restore-dired-filename-prop): New function.
(wdired-change-to-wdired-mode): Add it to after-change-functions.
(wdired-change-to-dired-mode): Remove it from after-change-functions.
(wdired-finish-edit): Move invocation of
wdired-change-to-dired-mode below invocation of wdired-do-renames,
so that the latter runs wdired--restore-dired-filename-prop, but
above the invocation of revert-buffer to avoid using
wdired-revert, which changes back to wdired-mode.
(wdired-search-and-rename): Wrap renaming in unwind-protect and if
user types C-g when prompted to change the file name, make sure we
return to dired-mode.
This is a fairly minimal fix for the release branch; a more
comprehensive fix is on master, so do not merge this to master.
* lisp/wdired.el (wdired-search-and-rename): Remove dired-filename
text property in order to find new filename when it only partially
replaces old filename (bug#32173). If user quits before renaming
succeeds, restore the dired-filename text property.
* lisp/simple.el (what-cursor-position): Revert ad-hoc change
to work around tis620-2533 charset.
* lisp/w32-fns.el: Use thai-iso8859-11 instead of tis620-2533.
* lisp/international/mule-conf.el (tis620-2533): Now an alias
for thai-iso8859-11, not a separate character set.
* lisp/international/fontset.el (charset-script-alist): Add
thai-iso8859-11; fix entries for greek and hebrew.
(font-encoding-alist, font-encoding-charset-alist): Use
thai-iso8859-11 instead of tis620-2533.
* lisp/descr-text.el (describe-char): Remove the ad-hoc code
that assigns eight-bit-control characters to the eight-bit
charset.
