* doc/lispref/nonascii.texi (Character Properties):
Avoid duplication of Unicode names. Reformat examples to fit in
narrow pages.
* doc/lispref/objects.texi (General Escape Syntax):
Simplify and better-organize explanation of \N{...} escapes.
* src/character.h (CHAR_SURROGATE_PAIR_P): Remove; unused.
(char_surrogate_p): New inline function.
* src/lread.c: Do not include string.h; no longer needed.
(invalid_character_name, check_scalar_value): Remove; the ideas
behind these functions are now bundled into character_name_to_code.
(character_name_to_code): Remove undocumented support for "CJK
IDEOGRAPH-XXXX" names, as "U+XXXX" suffices. Reject monstrosities
like "\N{U+-0}" and null bytes in \N escapes. Reject floating
point in \N escapes instead of returning garbage. Use
AUTO_STRING_WITH_LEN to lessen pressure on the garbage collector.
* test/src/lread-tests.el (lread-char-number, lread-char-name)
(lread-string-char-number, lread-string-char-name):
Test runtime behavior, not compile-time, as the test framework
is not set up to test compile-time.
(lread-char-surrogate-1, lread-char-surrogate-2)
(lread-char-surrogate-3, lread-char-surrogate-4)
(lread-string-char-number-2, lread-string-char-number-3):
New tests.
(lread-string-char-number-1): Rename from lread-string-char-number.
The manuals often used quotes ``...'' when it is better to use @dfn or
@code or capitalized words or no quoting at all. For example, there is
no need for the `` and '' in “if a variable has one effect for
@code{nil} values and another effect for ``non-@code{nil}'' values”.
Reword the Emacs, Lisp intro, and Lisp reference manuals to eliminate
unnecessary quoting like this, and to use @dfn etc. instead when called
for (Bug#21472).
* doc/lispref/objects.texi (Finalizer Type): New section
(Type Predicates): Mention finalizers in `type-of' documentation.
* doc/lispref/elisp.texi (Top): Link to finalizer type.
* src/data.c (Ftype_of): Make `type-of' work with finalizers.
(syms_of_data): Register Qfinalizer.
* src/print.c (print_object): Print whether a finalizer has
been called.
* test/automated/finalizer-tests.el (finalizer-object-type): Test that
`type-of' works correctly for finalizers.
* numbers.texi (Numbers, Integer Basics, Float Basics):
Document the basics a bit more precisely. Say more clearly
that Emacs floating-point numbers are IEEE doubles on all
current platforms. Give more details about frexp.
Say more clearly that '1.' is an integer.
(Predicates on Numbers): Fix wholenump typo.
* objects.texi (Integer Type): Adjust to match numbers.texi.
* commands.texi, customize.texi, display.texi, elisp.texi, files.texi:
* frames.texi, hash.texi, internals.texi, keymaps.texi, lists.texi:
* minibuf.texi, nonascii.texi, numbers.texi, objects.texi, os.texi:
* processes.texi, streams.texi, strings.texi, text.texi:
* variables.texi, windows.texi:
Hyphenate "floating-point" iff it precedes a noun.
Reword to avoid nouns and hyphenation when that's easy.
Prefer "integer" to "integer number" and "is floating point"
to "is a floating point number".
Prefer "@minus{}" to "-" when it's a minus.
Be more systematic about using "@." (not ".") at end of sentence that
ends in a capital letter, and about appending "@:" after non-ends of
sentences that end in a lower case letter followed by "." followed by
whitespace. Omit unnecessary use of "@:" and "@.". Similarly for "?"
and "!". Be more consistent about putting a comma after "i.e." and
"e.g."; this is the typical American style and it's easier to code in
Texinfo.
Fixes: debbugs:12973
* objects.texi (General Escape Syntax): Clarify the explanation of
escape sequences.

(Activation of Advice): Specifying the ACTIVATE flag in defadvice
is not abnormal.
(Advising Primitives): Node deleted; ad-define-subr-args has been
removed.
* doc/lispref/compile.texi (Speed of Byte-Code): Use float-time in example.
(Compilation Functions): Note that the log uses Compilation mode.
Don't discuss the contents of byte-code function object here.
(Compilation Functions): De-document internal function byte-code.
(Docs and Compilation): Minor clarifications.
* doc/lispref/objects.texi (Byte-Code Type): Add xref to Byte-Code Function
Objects.

information about starting docstrings with *. De-document
user-variable-p.
(Tips for Defining): Remove an unimportant discussion of quitting
in the middle of a load.
(Accessing Variables, Setting Variables): Discuss lexical binding.

(Scope, Extent, Impl of Scope): Nodes deleted.
(Dynamic Binding): New node, with material from Scope, Extent, and
Impl of Scope nodes.
(Dynamic Binding Tips): Rename from Using Scoping.

operating system signals. Refer to save-buffers-kill-terminal
instead of save-buffers-kill-emacs.
