++ Fix reordering of bracket characters in isolates.
++ * bidi.c (bidi_cache_find): Rename the argument NEUTRALS_OK to
++ RESOLVED_ONLY; when non-zero, return from the cache only fully
++ resolved states. All callers changed.
++ (CANONICAL_EQU): New macro.
++ (PUSH_BPA_STACK): Use it to push onto the BPA stack the canonical
++ equivalent of the paired closing bracket character.
++ (bidi_find_bracket_pairs): Set the bracket_pairing_pos member to
++ the default non-negative value, to be checked later in
++ bidi_resolve_brackets. Use CANONICAL_EQU to test candidate
++ characters against those pushed onto the BPA stack.
++ (bidi_record_type_for_neutral): New function.
++ (bidi_resolve_brackets): Record next_for_neutral and
++ prev_for_neutral when embedding level gets pushed. Force
++ resolution of bracket pairs when entering a level run that was not
++ yet BPA-resolved.
++ (bidi_resolve_neutral): Add assertions before calling
++ bidi_resolve_neutral_1.
++ (bidi_level_of_next_char): Remove the code that attempted to
++ resolve unresolved neutrals; that is now done by
++ bidi_resolve_neutral.
++
+ * w32select.c (owner_callback): Mark with ALIGN_STACK attribute.

+
+ * xterm.c (x_draw_hollow_cursor): Fix display of hollow cursor on
+ 1-pixel R2L characters.

+
+ * bidi.c (bidi_find_bracket_pairs): Avoid a loop that does nothing
+ useful.
+
+2014-10-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bidi.c (bidi_find_bracket_pairs): Initialize local var.
+ This pacifies GCC 4.9.1 with --enable-gcc-warnings.
+ It's not clear to me whether the initialization is needed,
+ but it can't hurt so I played it safe.
+
+2014-10-15 Stefan Monnier <monnier@iro.umontreal.ca>
+
+ * lisp.mk (lisp): Add emacs-lisp/eldoc.elc.
+
+2014-10-15 Eli Zaretskii <eliz@gnu.org>
+
+ Update the bidirectional reordering engine for Unicode 6.3 and 7.0.
+ * 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): Rename 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): Modify 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 longer accepts a level,
+ instead accepts a flag telling it whether it is okay to return
+ unresolved neutrals.
+ (bidi_initialize): Initiate and staticpro the bracket-type uniprop
+ 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).
+ (bidi_resolve_weak): Adapt to changes in struct members.
+ (FLAG_EMBEDDING_INSIDE, FLAG_OPPOSITE_INSIDE, MAX_BPA_STACK)
+ (STORE_BRACKET_CHARPOS, PUSH_BPA_STACK): New macros.
+ (bidi_resolve_neutral): Call bidi_resolve_brackets to handle the
+ 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.
+
+ * 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.
+
+ * 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.
+
+ * term.c (append_glyph, append_composite_glyph)
+ (append_glyphless_glyph): Convert aborts to assertions.
+
+ * .gdbinit (pgx): Display the character codepoint, resolved level,
+ and bidi type also for glyphless glyphs.

+
+ Avoid unwanted point motion in Fline_beginning_position.
+ * lisp.h (scan_newline_from_point): Add prototype.
+ * search.c (scan_newline_from_point): New function, refactored from...
+ * cmds.c (Fforward_line): ...adjusted user.
+ * editfns.c (Fline_beginning_position): Use scan_newline_from_point
+ and simplify the former since the latter doesn't move point.
