* doc/lispref/display.texi (Size of Displayed Text):
* lisp/international/mule-util.el (truncate-string-to-width):
Document caveats of using 'truncate-string-to-width' when
character composition is involved.
* lisp/emacs-lisp/subr-x.el (string-limit):
* doc/lispref/strings.texi (Creating Strings): Improve the
documentation of 'string-limit'.
* lisp/international/mule-util.el (filepos-to-bufferpos): Give
better errors on `exact' with unknown line endings, and guess at
Unix if `approximate' (bug#36573).
(bufferpos-to-filepos): Ditto.
* lisp/international/mule-util.el (truncate-string-ellipsis):
Use Unicode hex escapes instead of named escapes here, because \N{...}
is not available during bootstrapping. (Bug#41250)
* lisp/international/mule-util.el (truncate-string-ellipsis): Doc
fix.
* doc/lispref/display.texi (Size of Displayed Text): Improve
wording and accuracy of the documentation of
'truncate-string-to-width'. Document the function
'truncate-string-ellipsis'.
* etc/NEWS: Improve the wording of the entry for
'truncate-string-to-width'.
* lisp/international/mule-util.el (truncate-string-ellipsis):
Change the default value to nil.
(truncate-string-ellipsis): New function.

function 'truncate-string-ellipsis'.
* lisp/tab-bar.el (tab-bar-tab-name-truncated):

Take advantage of the improvement of the ellipsis default value
in truncate-string-to-width and truncate-string-ellipsis.
* doc/lispref/display.texi (Size of Displayed Text):
Improve description of truncate-string-ellipsis.
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-put-tag): Use
this to allow using commands like `C-s' to search for even
truncated bits.
* lisp/international/mule-util.el (truncate-string-to-width):
Allow using text properties to truncate strings instead of
actually truncating strings (bug#17782).
* lisp/international/mule-util.el (char-displayable-p): Move
from here...
* lisp/international/mule.el (char-displayable-p): ...to
here. This avoids always loading mule-util at startup due
to a call to 'char-displayable-p' in
'startup--setup-quote-display'.
I looked through all instances of most-negative-fixnum
and most-positive-fixnum in the Lisp source code, and
when it was easy I removed assumptions that integers
fit in fixnums. The remaining instances are either
nontrivial to fix, or are inherent to the algorithm.
* lisp/arc-mode.el (archive-l-e): Do not convert to float,
since we have bignums now. All uses changed.
* lisp/calc/calc.el (math-bignum):
Don’t special-case most-negative-fixnum.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
The primary speedup comes from the optimizing lookup-nested-alist and
set-nested-alist for the case where the key is a string. This brings
the time down to less than half the original.
* lisp/international/mule-util.el (lookup-nested-alist)
(set-nested-alist): Use `assq' instead of `assoc' when KEYSEQ is a
string.
* lisp/international/ja-dic-cnv.el (skkdic-collect-okuri-nasi)
(skkdic-convert-okuri-nasi): Use progress-reporter functions instead
of calculating ratio of work done inline.
(skkdic-reduced-candidates): Call `char-category-set' on the first
character of the string directly, instead of using a regexp for the
character category.
(skkdic--japanese-category-set): New constant.
(skkdic-collect-okuri-nasi): Just set
`skkdic-okuri-nasi-entries-count' at once at the end rather than
updating it throughout the loop.
(skkdic-convert-postfix skkdic-convert-prefix)
skkdic-get-candidate-list, skkdic-collect-okuri-nasi)
(skkdic-extract-conversion-data): Use `match-string-no-properties'
instead of `match-string'.

This should help Emacs work better out-of-the-box on Linux consoles,
which have only limited support for displaying Unicode characters.
Also, undo the recent change that caused text-quoting-style to
affect quote display on terminals, so that the two features are
independent. See Alan Mackenzie in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00244.html
Finally, add a style parameter to startup--setup-quote-display,
so that this function can also be invoked after startup, with
different styles depending on user preference at the time.
* configure.ac: Check for linux/kd.h header.
* doc/emacs/display.texi (Text Display): Document quote display.
* doc/lispref/display.texi (Active Display Table):
* etc/NEWS:
* lisp/startup.el (startup--setup-quote-display, command-line):
text-quoting-style no longer affects quote display.
* doc/lispref/frames.texi (Terminal Parameters): Fix typo.
* lisp/international/mule-util.el (char-displayable-p):
* lisp/startup.el (startup--setup-quote-display):
On a text terminal supporting glyph codes, use the reported
glyph codes instead of the terminal coding system, as this
is more accurate on the Linux console.
* lisp/startup.el (startup--setup-quote-display):
New optional arg STYLE.
* src/fontset.c (Finternal_char_font):
Report glyph codes for a text terminal, if they are available.
Currently this is supported only for the Linux console.
* src/termhooks.h (struct terminal): New member glyph-code-table.
* src/terminal.c [HAVE_LINUX_KD_H]: Include <errno.h>, <linux/kd.h>.
(calculate_glyph_code_table) [HAVE_LINUX_KD_H]: New function.
(terminal_glyph_code): New function.
* lisp/info.el (Info-read-subfile): Add to the returned value the
length of subfile preamble, after converting it to file's byte
offset, as expected by the caller. Use bufferpos-to-filepos.
(Info-find-node-2): If searching for a node with a
1000-character slop fails, try again with a 10000-character slop,
to account for known bugs in Texinfo 5.0 and 5.1. (Bug#21055)
* lisp/international/mule-util.el (bufferpos-to-filepos): New
function.
* etc/NEWS: Mention bufferpos-to-filepos.
* lisp/international/mule-util.el (filepos-to-bufferpos):
Fix typo. Move non-exact check to the utf-16 branch (the only one
affected). Don't use byte-to-position for the utf-16 case.
* lisp/international/mule-util.el (filepos-to-bufferpos): Remove
test for utf-8-emacs. Exempt single-byte encodings from the
'use-exact' path when QUALITY is 'exact'. Test UTF-16 encodings
for BOM before subtracting 2 bytes. Use 'identity' when adjusting
UTF-16 encoded files for CR-LF EOLs.
* lisp/international/mule-util.el (filepos-to-bufferpos--dos):
Don't barf if F returns nil for some argument.
(filepos-to-bufferpos): Expand to support UTF-16 and not assume
that every encoding of type 'charset' is single-byte.
* lisp/international/mule-util.el (filepos-to-bufferpos--dos):
New auxiliary function, extracted from filepos-to-bufferpos.
Make sure it terminates.
(filepos-to-bufferpos): Use it to fix the latin-1-dos case.
Add support for the `exact' quality.
* lisp/international/mule-util.el (filepos-to-bufferpos): Fix EOL
offset calculation, and make it conditional on the eol-type of the
file's encoding. (Bug#20825)
* lisp/international/mule-util.el: Use lexical-binding.
(filepos-to-bufferpos): New function.
* lisp/info.el (Info-find-in-tag-table-1): Use 0-based file positions.
(Info-find-node-2): Use filepos-to-bufferpos (bug#20704).
(Info-read-subfile, Info-search): Use 0-based file positions.
* test/automated/mule-util.el: New file, with tests extracted from
lisp/international/mule-util.el.
Copyright years based on when the original test-suite comment was
added to lisp/international/mule-util.el (in 2002).
* lisp/international/mule-util.el: Extract comment test-suite out to
separate file.
