src/bidi.c (bidi_ignore_explicit_marks_for_paragraph_level): Remove
variable.
(bidi_get_type): Return the isolate initiators and terminator
types.
(bidi_isolate_fmt_char, bidi_paired_bracket_type)
(bidi_fetch_char_skip_isolates, find_first_strong_char)
(bidi_find_bracket_pairs, bidi_resolve_brackets): New functions.
(bidi_set_sos_type): Renamed from bidi_set_sor_type and updated
for the new features.
(bidi_push_embedding_level, bidi_pop_embedding_level): Update to
push and pop correctly for isolates.
(bidi_remember_char): Modified to accept an additional argument
and record the bidi type according to its value.
(bidi_cache_iterator_state): Accept an additional argument to only
update an existing state. Handle the new members of struct bidi_it.
(bidi_cache_find): Arguments changed: no lnger accepts a level,
instead accepts a flag telling it whether it is okay to return
unresolved neutrals.

table. Initialize new isolate-related members.
(bidi_paragraph_init): Some code factored out into
find_first_strong_char.
(bidi_resolve_explicit_1): Function deleted, its code incorporated
into bidi_resolve_explicit.
(bidi_resolve_explicit): Support the isolate initiators and
terminator. Fix handling of embeddings and overrides according to
new UBA requirements. Record information about previously seen
characters here (moved from bidi_level_of_next_char).

paired bracket resolution. Handle isolate initiators and
terminator.
(bidi_type_of_next_char): Remove unneeded code for BN limit.
(bidi_level_of_next_char): Move the code that records information
about previous characters to bidi_resolve_explicit. Fix logic of
resolving neutrals and make sure their cache entries are updated.
Remove now unneeded special handling of PDF level.
src/dispextern.h (struct glyph): Enlarge the width of resolved_level.
(BIDI_MAXDEPTH): New macro, renamed from BIDI_MAXLEVEL and
enlarged per Unicode 6.3.
(enum bidi_bracket_type_t): New data type.
(struct bidi_saved_info): Leave only 2 type members out of 4.
Remove bytepos.
(struct bidi_stack): Add members necessary to support isolating
sequences.
(struct bidi_it): Add new members necessary to support isolating
sequences and bracket pair resolution.
src/xdisp.c (Fbidi_resolved_levels): New function.
(syms_of_xdisp): Defsubr it.
(append_glyph, append_composite_glyph, produce_image_glyph)
(append_stretch_glyph, append_glyphless_glyph): Convert aborts to
assertions.
(syms_of_xdisp) <inhibit-bidi-mirroring>: New variable.
src/term.c (append_glyph, append_composite_glyph)
(append_glyphless_glyph): Convert aborts to assertions.
src/.gdbinit (pgx): Display the character codepoint, resolved level,
and bidi type also for glyphless glyphs.
lisp/simple.el (what-cursor-position): Update to support the new bidi
characters.
lisp/descr-text.el (describe-char): Update to support the new bidi
characters.
admin/unidata/unidata-gen.el (unidata-prop-alist): New properties
'paired-bracket' and 'bracket-type', in support of the UBA 6.3.
(unidata-gen-table): Support PROP-IDX being a function.
(unidata-describe-bidi-bracket-type, unidata-gen-brackets-list)
(unidata-gen-bracket-type-list): New functions.
(unidata-check): Support checking the 'bracket-type' attribute.
(unidata-gen-files): Don't create backups for uni-*.el files.
admin/unidata/Makefile.in (${unidir}/charprop.el): Depend on
BidiMirroring.txt and BidiBrackets.txt.
admin/unidata/BidiBrackets.txt: New file, from Unicode.
etc/NEWS: Mention the UBA implementation update.
etc/HELLO: Remove now unneeded directional control characters.
doc/lispref/nonascii.texi (Character Properties): Document the new
properties 'bracket-type' and 'paired-bracket'.
doc/lisprefdisplay.texi (Bidirectional Display): Update the version of the
UBA to which we are conforming.
test/BidiCharacterTest.txt: New file, from Unicode.
test/biditest.el: New file.

README for the Emacs Lisp Reference Manual.
* This directory contains the texinfo source files for the Emacs Lisp
Reference Manual.
* Report bugs in the Lisp Manual (or in Emacs) using M-x report-emacs-bug.
To ask questions, use the help-gnu-emacs mailing list.
* The Emacs Lisp Reference Manual is quite large. It totals around
1100 pages in smallbook format; the info files total around 3.0 megabytes.
* You can format this manual for Info, for printing hardcopy using TeX,
or for HTML.
* You can buy nicely printed copies from the Free Software Foundation.
Buying a manual from the Free Software Foundation helps support our GNU
development work. See <http://shop.fsf.org/>.
(At time of writing, this manual is out of print.)
* The master file for formatting this manual for Tex is called `elisp.texi'.
It contains @include commands to include all the chapters that make up
the manual.
* This distribution contains a Makefile that you can use with GNU Make.
** To make an Info file, you need to install Texinfo, then run `make info'.
** Use `make elisp.pdf' or `make elisp.html' to create PDF or HTML versions.
