http://lists.gnu.org/archive/html/emacs-devel/2010-03/msg01280.html
* replace.el (occur-accumulate-lines): Add optional arg `pt'.
(occur-engine): Add local variables `ret', `prev-after-lines',
`prev-lines'. Use more arguments for `occur-context-lines'.
Set first elem of its returned list to `data', and the second elem
to `prev-after-lines'. Don't print the separator line.
In the end, print remaining context after-lines.
(occur-context-lines): Add new arguments `begpt', `endpt',
`lines', `prev-lines', `prev-after-lines'. Rewrite to combine
after-lines of the previous match with before-lines of the
current match and not overlap them. Return a list with two
values: the output line and the list of context after-lines.
* search.texi (Other Repeating Search): Remove line that `occur'
can not handle multiline matches.
* occur-testsuite.el (occur-tests): Add tests for context lines.
Makefile.in (obj): Include bidi.o.
(bidi.o): New target.
makefile.w32-in (OBJ1): Add $(BLD)/bidi.$(O).
($(BLD)/bidi.$(O)): New target.
bidi.c: New file.
buffer.h (struct buffer): New members bidi_display_reordering
and bidi_paragraph_direction.
buffer.c (init_buffer_once): Initialize bidi_display_reordering
and bidi_paragraph_direction.
(syms_of_buffer): Declare Lisp variables bidi-display-reordering
and bidi-paragraph-direction.
(Fbuffer_swap_text): Swap the values of
bidi_display_reordering and bidi_paragraph_direction.
dispextern.h (BIDI_MAXLEVEL, BIDI_AT_BASE_LEVEL): New macros.
(bidi_type_t, bidi_dir_t): New types.
(bidi_saved_info, bidi_stack, bidi_it): New structures.
(struct it): New members bidi_p, bidi_it, paragraph_embedding,
prev_stop, base_level_stop, and eol_pos.
(bidi_init_it, bidi_get_next_char_visually): New prototypes.
(IT_STACK_SIZE): Enlarge to 5.
(struct glyph_row): New member reversed_p.
<string_buffer_position>: Update prototype.
(PRODUCE_GLYPHS): Set the reversed_p flag in the iterator's
glyph_row if bidi_it.paragraph_dir == R2L.
(struct glyph): New members resolved_level and bidi_type.
dispnew.c (direct_output_forward_char): Give up if we need bidi
processing or buffer's direction is right-to-left.
(prepare_desired_row): Preserve the reversed_p flag.
(row_equal_p): Compare the reversed_p attributes as well.
xdisp.c (init_iterator): Initialize it->bidi_p. Call
bidi_init_it and set it->paragraph_embedding from the current
buffer's value of bidi_paragraph_direction.
(reseat_1): Initialize bidi_it.first_elt.
(set_iterator_to_next, next_element_from_buffer): Use the value of
paragraph_embedding to determine the paragraph direction.
(set_iterator_to_next): Under bidi reordering, call
bidi_get_next_char_visually. Call bidi_paragraph_init if the
new_paragraph flag is set in the bidi iterator.
(next_element_from_buffer): If bidi_it.first_elt is set,
initialize paragraph direction and find the first character to
display in the visual order. If reseated to a middle of a line,
prime the bidi iterator starting at the line's beginning. Handle
the situation where we overstepped stop_charpos due to
non-linearity of the bidi iteration. Likewise for when we back up
beyond the previous stop_charpos. When moving across stop_charpos,
record it in prev_stop.
(display_line): Set row->end and it->start for the next row to the
next character in logical order. Always extend reversed_p rows to
the end of line, even if they end at ZV. Copy the reversed_p flag
to the next glyph row. Keep calling set_cursor_from_row for
bidi-reordered rows even if we already have a possible candidate
for cursor position. Set row_end after all the row's glyphs have
been produced, by looping over the glyphs. Record the position
after EOL in it->eol_pos, and use it to set end_pos of the last
row produced for a continued line.
<Qright_to_left, Qleft_to_right>: New variables.
(syms_of_xdisp): Initialize and staticpro them.
(string_buffer_position_lim): New function.
(string_buffer_position): Most of code moved to
string_buffer_position_lim. Last argument and return value are
now EMACS_INT; all callers changed.
(set_cursor_from_row): Rewritten to support bidirectional text and
reversed glyph rows.
(text_outside_line_unchanged_p, try_window_id): Disable
optimizations if we are reordering bidirectional text and the
paragraph direction can be affected by the change.
(append_glyph, append_composite_glyph)
(produce_image_glyph, append_stretch_glyph): Set the
resolved_level and bidi_type members of each glyph.
(append_glyph): If the glyph row is reversed, prepend the glyph
rather than appending it.
(handle_stop_backwards): New function.
(reseat_1, pop_it, push_it): Set prev_stop and base_level_stop.
(reseat): call handle_stop_backwards to recompute prev_stop and
base_level_stop for the new position.
(handle_invisible_prop): Under bidi iteration, skip invisible text
using bidi_get_next_char_visually. If we are `reseat'ed, init the
paragraph direction. Update IT->prev_stop after skipping
invisible text.
(move_it_in_display_line_to): New variables prev_method
and prev_pos. Compare for strict equality in
BUFFER_POS_REACHED_P.
(try_cursor_movement): Examine all the candidate rows that occlude
point, to return the best match. If rows are bidi-reordered
and point moved backwards, back up to the row that is not a
continuation line, and start looking for a suitable row from
there.
term.c (append_glyph): Reverse glyphs by pre-pending them,
rather than appending, if the glyph_row's reversed_p flag is set.
Set the resolved_level and bidi_type members of each glyph.
.gdbinit (pbiditype): New command.
(pgx): Use it to display bidi level and type of the glyph.
(pitx): Display some bidi information about the iterator.
(prowlims, pmtxrows): New commands.
files.el: Make bidi-display-reordering safe variable for boolean
values.
mule.texi (International): Mention support of bidirectional editing.
(Bidirectional Editing): New section.
HELLO: Reorder Arabic and Hebrew into logical order, and
insert RLM before the opening paren, to make the display more
reasonable. Add setting for bidi-display-reordering in the local
variables section.
NEWS: Mention initial support for bidirectional editing.
* mm-decode.el (mm-add-meta-html-tag): Added option to override the
charset.
* gnus-art.el (gnus-article-browse-html-parts): Force the correct
charset into the <meta> tag when the article is encoded to utf-8.
* gnus-art.el (gnus-article-browse-delete-temp-files): Delete
directories as well.
(gnus-article-browse-html-parts): Work for images that do not specify
file names; delete temp directory when quitting; insert header at the
right place; use file: scheme for image files.
2010-03-30 Eric Schulte <schulte.eric@gmail.com>
* gnus-art.el (gnus-article-browse-html-save-cid-image): New function.
(gnus-article-browse-html-parts): Use it to make temporary cid image
files in addition to html file so that browser may display them.
doc/emacs/mule.texi (International): Mention support of
bidirectional editing.
(Bidirectional Editing): New section.
etc/HELLO: Reorder Arabic and Hebrew into logical order, and

* auth-source.el (auth-sources): Change default to be simpler. Explain
about Secret Service API sources. Improve Customize options.
(auth-source-pick): Change to accept any number of search parameters.
Implement fallbacks iteratively, not recursively. Add scoring on the
second pass and sort by score. Call Secret Service API when needed.
(auth-source-user-or-password): Use it. Call Secret Service API
directly when needed to get the user name and the password.
bidi.c (bidi_get_next_char_visually): Improve commentary.
dispextern.h (PRODUCE_GLYPHS): Set the reversed_p flag in the
iterator's glyph_row here.
xdisp.c (handle_invisible_prop, set_iterator_to_next)
(next_element_from_buffer): Don't set the reversed_p flag in the
iterator's glyph_row here.
makefile.w32-in ($(TIT), $(MISC_DIC), leim-list.el): Enclose the
argument of "-l" in $(ARGQUOTE), in case it includes blanks or
other special characters.

code in a comment.
