* data.c (Fmake_variable_buffer_local, Fmake_local_variable):

(Fmake_variable_frame_local): Add the same test.
xdisp.c [HAVE_WINDOW_SYSTEM]: Add prototype for
append_stretch_glyph.
(set_cursor_from_row) <cursor_x>: Remove unused variable. Fix
off-by-one error in computing x at end of text in the row.
(append_stretch_glyph): In reversed row, prepend the glyph rather
than append it. Set resolved_level and bidi_type of the glyph.
(extend_face_to_end_of_line): If the row is reversed, prepend a
stretch glyph whose width is such that the rightmost glyph will be
drawn at the right margin of the window. Fix off-by-one error on
TTY frames in testing whether a line needs face extension. Fix
face extension at ZV. If this is the last glyph row, use
DEFAULT_FACE_ID, to avoid painting the rest of the window with the
region face.

MATRIX_ROW_CONTINUATION_LINE_P instead of testing value of
row->continuation_lines_width.

which happens with R2L glyph rows. Fixes a crash when inserting a
character at end of an R2L line.

treat them as having zero-width characters. Improve comments.
Don't reverse pos_before and pos_after for reversed glyph rows.
Set cursor.x to negative value when the cursor might be on the
left fringe.

left fringe, not the right one.

draw cursor on the left fringe.

cursor on the left fringe.

the cursor is on the left fringe.
(set_window_cursor_after_update): Limit cursor's hpos by -1 from
below, not by 0, for when the cursor is on the left fringe.

glyph rows.
(append_composite_glyph): In R2L rows, prepend the glyph rather
than appending it.

rather than append it. Set up the resolved_level and bidi_type
attributes of the appended glyph.
(produce_special_glyphs): Mirror the backslash continuation
character in R2L lines.
xdisp.c (unproduce_glyphs): New function.
(display_line): Use it when produced glyphs are discarded from R2L
glyph rows.
(append_composite_glyph): In R2L rows, prepend the glyph rather
than appending it.
term.c (append_composite_glyph): In R2L rows, prepend the glyph
rather than append it. Set up the resolved_level and bidi_type
attributes of the appended glyph.
Basically, this makes the structure of buffer-local values and object
forwarding explicit in the type of Lisp_Symbols rather than use
special Lisp_Objects for that. This tends to lead to slightly more
verbose code, but is more C-like, simpler, and makes it easier to make
sure we handled all cases, among other things by letting the compiler
help us check it.
