* src/syntax.c (Fforward_comment): Prevent the loop for COUNT < 0
from going outside the valid range of character/byte positions.

"comment-fence" and "string-fence" as alternative names of 2
syntax classes.
and cannot be combined with other ways of applying syntax-table text
properties.

Remove function quoting from lambda in examples where it still occurs,

* doc/lispref/syntax.texi (Parser State): mention parse-partial-sexp as a
function returning a parser state, and the function to which one supplies a
parser state as an argument for continued parsing.
Refine the documentation of syntax-ppss-context, and correct the text
introducing it and another function.
I audited use of lsh in the Lisp source code, and fixed the
glitches that I found. While I was at it, I replaced uses of lsh
with ash when either will do. Replacement is OK when either
argument is known to be nonnegative, or when only the low-order
bits of the result matter, and is a (minor) win since ash is a bit
more solid than lsh nowadays, and is a bit faster.
* lisp/calc/calc-ext.el (math-check-fixnum):
Prefer most-positive-fixnum to (lsh -1 -1).
* lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width,
prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1
32)) (Bug#32485#11).
* lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode):
Tighten sanity-check for bytecode overflow, by checking that the
result of (ash pc -8) is nonnegative. Formerly this check was not
needed since lsh was used and the number overflowed differently.
* lisp/net/dns.el (dns-write): Fix some obvious sign typos in
shift counts. Evidently this part of the code has never been
exercised.

Move detailed discussion of text-quoting-style here.
Add discussion about how to output grave accent and apostrophe in
documentation and messages. Adjust xrefs to point to this section
when appropriate.
* etc/NEWS: text-quoting-style semantics have not changed.
Do this by adding a new field to the parser state: the syntax of the last
character scanned, should that be the first char of a (potential) two char
construct, nil otherwise.
This should make the parser state complete.
Also document element 9 of the parser state. Also refactor the code a bit.
* src/syntax.c (struct lisp_parse_state): Add a new field.
(SYNTAX_FLAGS_COMSTARTEND_FIRST): New function.
(internalize_parse_state): New function, extracted from scan_sexps_forward.
(back_comment): Call internalize_parse_state.
(forw_comment): Return the syntax of the last character scanned to the caller
when that character might be the first of a two character construct.
(Fforward_comment, scan_lists): New dummy variables, passed to forw_comment.
(scan_sexps_forward): Remove a redundant state parameter. Access all `state'
information via the address parameter `state'. Remove the code which converts
from external to internal form of `state'. Access buffer contents only from
`from' onwards. Reformulate code at the top of the main loop correctly to
recognize comment openers when starting in the middle of one. Call
forw_comment with extra argument (for return of syntax value of possible first
char of a two char construct).
(Fparse_partial_sexp): Document elements 9, 10 of the parser state in the
doc string. Clarify the doc string in general. Call
internalize_parse_state. Take account of the new elements when consing up the
output parser state.
* doc/lispref/syntax.texi: (Parser State): Document element 9 and the new
element 10. Minor wording corrections (remove reference to "trivial
cases").
(Low Level Parsing): Minor corrections.
* etc/NEWS: Note new element 10, and documentation of element 9 of parser
state.
* doc/lispref/syntax.texi (Syntax Flags): State that only comments of the same
style are recognized inside nestable comments.
(Low-Level Parsing): Clarify that parsing will stop after the start or end of
UNNESTED comments.
Use this in C, C++, and Objective C Modes. Fixes bug#22246
* src/syntax.c (comment-end-can-be-escaped): New buffer local variable.
(forw-comment, back-comment): On encountering an end of comment character,
test whether it is escaped when `comment-end-can-be-escaped' is non-nil.
* doc/lispref/syntax.texi (Control Parsing): Describe
`comment-end-can-be-escaped'.
* etc/NEWS (Lisp Changes): Describe `comment-end-can-be-escaped'.
* lisp/progmodes/cc-langs.el: New c-lang-setvar `comment-end-can-be-escaped'.
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).

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.
