stream.el provides an implementation of streams. Streams are
implemented as delayed evaluation of cons cells.
The implementation is close to the one in the SICP
book (https://mitpress.mit.edu/sicp/full-text/book/book-Z-H-24.html).
Streams could be created from any sequencial input data, including
sequences, , making operation on them lazy, a set of 2 forms (first and
rest), making it easy to represent infinite sequences, buffers (by
character), buffers (by line), buffers (by page), IO streams, orgmode
table cells, etc.
* lisp/emacs-lisp/stream.el: New file.
* test/automated/stream-tests.el: New file.
* 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/help-fns.el (describe-symbol-backends): New var.
(help-xref-stack-item): Declare.
(describe-symbol): Rename from describe-function-or-variable.
Rewrite using describe-symbol-backends instead of help-xref-interned.
* lisp/help.el (help-map): Use it.
* lisp/help-mode.el (help-symbol, help-follow-symbol): Use it.
(help-xref-interned): Make it into an obsolete alias.
* etc/NEWS:
* doc/lispref/frames.texi (Mouse Tracking): Document the special
effect of setting 'track-mouse' to 'dragging'.
* lisp/textmodes/artist.el (artist-mouse-draw-continously):
* lisp/ruler-mode.el (ruler-mode-mouse-drag-any-column-iteration):
* lisp/mouse-drag.el (mouse-drag-throw):
* lisp/mouse.el (mouse-drag-line): Set 'track-mouse' to 'dragging'
to avoid changes in the shape of the mouse pointer.
* src/xdisp.c (define_frame_cursor1): Don't change the mouse
pointer shape when do_mouse_tracking has the value of 'dragging',
not just any non-nil value. (Bug#20934)
(syms_of_xdisp): DEFSYM 'dragging'.
* lisp/progmodes/grep.el (grep-template, grep-find-template):
Update the description for <C>. (Bug#20728)
(grep-compute-defaults): Don't add the --color option to
grep-options. Only add it to grep-command.
(grep-expand-keywords): Expand the env value opts into <C>.
(grep-expand-template): Replace cf in the env with the opts list,
that can include -i and --color.
* lisp/progmodes/xref.el (xref-collect-matches): Do not remove
"--color=always" from the template, because we don't have to.
(isearch-character-fold-search, isearch--character-fold-extras)
(isearch--character-fold-table): New variable.
(isearch--character-folded-regexp): New function.
(isearch-search-fun-default): Use them.

Fix several problems with the recently-added custom variable
help-quote-translation where the code would quote inconsistently
in help buffers. Add support for quoting 'like this', which
is common in other GNU programs in ASCII environments. Change
help-quote-translation to use more mnemonic values: values are now the
initial quoting char, e.g., (setq help-quote-translation ?`) gets the
traditional Emacs help-buffer quoting style `like this'. Change the
default behavior of substitute-command-keys to match what's done in
set-locale-environment, i.e., quote ‘like this’ if displayable,
'like this' otherwise.
* doc/lispref/help.texi (Keys in Documentation): Document
new behavior of substitute-command-keys, and document
help-quote-translation.
* doc/lispref/tips.texi (Documentation Tips):
Mention the effect of help-quote-translation.
* etc/NEWS: Mention new behavior of substitute-command-keys,
and merge help-quote-translation news into it.
When talking about doc strings, mention new ways to type quotes.
* lisp/cedet/mode-local.el (overload-docstring-extension):
Revert my recent change to this function, which shouldn't be
needed as the result is a doc string.

(mode-local-describe-bindings-2):
* lisp/cedet/srecode/srt-mode.el (srecode-macro-help):

(help-fns--compiler-macro, help-fns--parent-mode)
(help-fns--obsolete, help-fns--interactive-only)

Use substitute-command-keys to ensure a more-consistent quoting
style in help buffers.
* lisp/cus-start.el (standard):
Document new help-quote-translation behavior.
* lisp/emacs-lisp/lisp-mode.el (lisp-fdefs):
* lisp/help-mode.el (help-xref-symbol-regexp, help-xref-info-regexp)
(help-xref-url-regexp):
* lisp/international/mule-cmds.el (help-xref-mule-regexp-template):

Also match 'foo', in case we're in a help buffer generated when
help-quote-translation is ?'.
* src/doc.c: Include disptab.h, for DISP_CHAR_VECTOR.
(LEFT_SINGLE_QUOTATION_MARK, uLSQM0, uLSQM1, uLSQM2, uRSQM0)
(uRSQM1, uRSQM2, LSQM, RSQM): New constants.

(Vhelp_quote_translation): Document new behavior.
* etc/NEWS: Update wording since Unicode 8.0 is no longer in draft
status.
* test/BidiCharacterTest.txt: Update from Unicode 8.0.
* admin/unidata/BidiMirroring.txt:
* admin/unidata/BidiBrackets.txt:
* admin/unidata/UnicodeData.txt: Update from Unicode 8.0.

(filepos-to-bufferpos): New function.
* lisp/info.el (Info-find-in-tag-table-1): Use 0-based file positions.

defcustom.

non-nil, call `checkdoc-package-keywords'.
(checkdoc-get-keywords): New defun.
(checkdoc-package-keywords): New command. Warns if the current file
has package.el-style keywords that aren't in `finder-known-keywords'.
* etc/NEWS: Add entry.
* lisp/emacs-lisp/checkdoc.el (checkdoc-error): When
`checkdoc-diagnostic-buffer' is set to "*warn*", print the warning
to the standard output.
(bug#20754)
Calls like (print FOO) could generate improperly encoded or
hard-to-read output if FOO contains characters outside the system
locale. Fix this by treating batch stdout and stderr like
interactive standard display, when it comes to transliterating and
encoding characters (Bug#20545).
* doc/emacs/mule.texi (Communication Coding):
* doc/lispref/display.texi (Active Display Table):
* doc/lispref/nonascii.texi (Locales):
* etc/NEWS:
* src/coding.c (syms_of_coding):
* src/dispnew.c (syms_of_display):
Document this.
* src/print.c: Include disptab.h.
(printchar_to_stream): New function, with much of the guts of the
old Fexternal_debugging_output, except this one also uses the
standard display table.
(printchar, strout, Fexternal_debugging_output): Use it.
* startup.el (command-line-1): When Emacs is given a file as an
argument and `initial-buffer-choice' is non-nil, display both the file
and `initial-buffer-choice'. For more than one file, show
`initial-buffer-choice' and *Buffer List*. Refactor display-changing
commands out of the command line arg parser.
(initial-buffer-choice): Clarify docstring.
This lets you easily insert quotes ‘like this’ by typing
quotes `like this', and similarly you can easily insert
quotes “like this” by typing quotes ``like this'' (Bug#20545).
* doc/emacs/basic.texi (Inserting Text):
* doc/emacs/modes.texi (Minor Modes):
* etc/NEWS: Document it.
* doc/emacs/text.texi (Quotation Marks): New section.

(electric-quote-string, electric-quote-paragraph):
New custom vars.

(electric-quote-mode, electric-quote-local-mode): New minor modes.
* lisp/progmodes/elisp-mode.el (emacs-lisp-mode):
Add curved single quotes to electric-pair-text-pairs.
Set electric-quote-string in this buffer.
So, for example, it turns "`abc'" into "‘abc’" (Bug#20385).
* doc/lispref/help.texi (Keys in Documentation):
* etc/NEWS: Document this.
* src/doc.c (Fsubstitute_command_keys): Implement it.

terminal-init-xterm-modify-other-keys.

terminal-init-xterm-bracketed-paste-mode.
(xterm--init-activate-set-selection): Rename from
terminal-init-xterm-activate-set-selection.
(xterm--selection-char): New function.
(gui-backend-set-selection): Use it. Use the &context to only apply
this method in terminals where we enabled the feature.
(gui-backend-get-selection): New method.
(tabulated-list-print): New optional argument, UPDATE. If
non-nil, the list is printed by only adding and deleting the
changed entries, instead of erasing the whole buffer. This method
is much faster when few or no entries have changed.
* doc/lispref/modes.texi (Tabulated List Mode): Document it.
* etc/NEWS: Document it.
(erc-network-hide-list, etc-channel-hide-list): New lists to define
message types per network/channel.

to its buffer, signal error before prompting for buffer name. Handle
`switch-to-buffer-in-dedicated-window'. (Bug#20472)
* doc/lispref/windows.texi (Switching Buffers): Document
`switch-to-buffer-in-dedicated-window'.
No-op by default, only kills term buffer if
`eshell-destroy-buffer-when-process-dies' is non-nil. (Bug#18108)
(eshell-destroy-buffer-when-process-dies): New custom to preserve
previous behavior.
