This also fixes the mishandling of "\N{CJK COMPATIBILITY
IDEOGRAPH-F900}", "\N{VARIATION SELECTOR-1}", etc.
Problem reported by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2016-04/msg00614.html
* doc/lispref/nonascii.texi (Character Codes), etc/NEWS: Document this.
* lisp/international/mule-cmds.el (char-from-name): New function.
(read-char-by-name): Use it. Document that "BED" is treated as
a name, not as a hexadecimal number. Reject out-of-range integers,
floating-point numbers, and strings with trailing junk.
* src/lread.c (character_name_to_code): Call char-from-name
instead of inspecting ucs-names directly, so that we handle
computed names like "VARIATION SELECTOR-1". Do not use an auto
string, since char-from-name might GC.
* test/src/lread-tests.el: Add tests for new behavior, and
fix some old tests that were wrong.
* lisp/emacs-lisp/find-func.el (find-library):
* lisp/help-mode.el (help-function-def, help-variable-def):
Run `find-function-after-hook' inside the help-function of the
buttons (bug#22583).
This allows the calling of c-restore-<>-properties from c-common-init without
the test suite giving spurious errors.
* lisp/progmodes/cc-engine.el (c-forward-<>-arglist): Remove the form that
sets face properties.
(c-forward-<>-arglist-recur): Reformulate the bit that handles types inside
template brackets using c-inside-<>-type-key. Don't bind
c-record-type-identifiers or c-record-found-types around the recursive call,
allowing positions of found types to flow back to the caller.
* lisp/progmodes/cc-langs.el (c-inside-<>-type-kwds, c-inside-<>-type-key):
new lang consts/var.
* lisp/progmodes/cc-mode.el (c-common-init): Don't remove
c-restore-<>-properties from the list of functions called at mode
initialization.
For example, "t1 *fn (t2 *b);".
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): Add new variable
at-decl-start, setting it to whether the putative decl starts immediately
after ; or { or }. Accept such a construct as a decl when at-decl-start is
non-nil.
* lisp/progmodes/cc-langs.el (c-pre-start-tokens): New language variable.
* lisp/w32-fns.el (w32-convert-standard-filename): Don't mirror
slashes into backslashes. This avoids producing ugly file names,
and is deemed no longer necessary, and should certainly be
unrelated to which shell is in use.
* lisp/vc/vc-hooks.el (vc-working-revision):
Remove the previous change.
(vc-state): Same. And update the old, incorrect comment about
unregistered files
(http://lists.gnu.org/archive/html/emacs-devel/2016-04/msg00526.html).
* test/lisp/vc/vc-tests.el (vc-test--state): Remove the check
calling `vc-state' on default-directory (VC state is undefined
for directories). Check that `vc-state' returns nil where it
returned `unregistered' before. Remove all checks comparing
invocations with the backend passed in explictly and without.
(vc-test--working-revision): Remove all checks comparing
invocations with the backend passed in explictly and without.
Update comments, and add a new one.

* lisp/textmodes/css-mode.el (css--property-values): Don't return
duplicate values.
* test/lisp/textmodes/css-mode-tests.el (css-test-property-values):
Take the above into account.
(css-test-property-values-no-duplicates): Test that duplicates aren't
returned by `css--property-values'.
* lisp/textmodes/css-mode.el (css--property-values): Cache computed
values.
* test/lisp/textmodes/css-mode-tests.el (css-test-property-value-cache):
New regression test for the above.
* url-http.el (url-http-user-agent-string): Compute User-Agent
string dynamically.
(url-http--user-agent-default-string): New function.
* url-vars.el (url-privacy-level): Allow `emacs' in list of
information not to send.
(url-user-agent): Add nil and `default' options; do not
pre-compute value.
* lisp/progmodes/sql.el (sql-product-alist): Allow _
characters in SQL prompts (bug#22596).
Fixes issue 22596, whereby "_" is now not considered a word constituent
character in sql-interactive-mode, so prompts like "foo_dev# " are not
correctly detected. Rather than piggy-back on the symbol table, we
explicitly match against alphanumeric chars or "_".
* lisp/emacs-lisp/autoload.el (autoload--non-timestamp): New constant.
(autoload-generate-file-autoloads, autoload-find-destination)
(update-directory-autoloads): Use autoload--non-timestamp.
* lisp/vc/vc-git.el (vc-git-mode-line-string): Use `substring'
instead of `replace-regexp-in-string', because REV can be nil
(e.g. when FILE is a directory, bug#23344), and we actually know
we only need the first 4 characters.
* src/xterm.c (x_set_window_size):
* src/w32term.c (x_set_window_size): Restore
do_pending_window_change calls after their stupid removal on
2015-08-31.
* 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.
* lread.c (invalid_character_name, check_scalar_value)
(parse_code_after_prefix, character_name_to_code): New helper
functions that use 'ucs-names' and parsing for CJK ideographs.
(read_escape): Use helper functions.
(syms_of_lread): New symbol 'ucs-names'.
* test/src/lread-tests.el: New tests; fix a couple of bugs in
existing tests.
* lread.c (init_character_names): New function.
(read_escape): Read Perl-style named character escape sequences.
(syms_of_lread): Initialize new variable 'character_names'.
* test/src/lread-tests.el (lread-char-empty-name): Add test file
for src/lread.c.
