negative number for the argument TOHPOS of compute_motion().
We don't need to calculate to (HPOS==0), but can stop immediately
when VPOS pasts HEIGHT.

rev_dir_bit to display right to left characters (not yet used).

(message): Use FRAME_MESSAGE_BUF_SIZE().
(redisplay_internal): Add canceling code for continuation at
wide-column.
(display_text_line): Don't just decrement left_edge->bufpos,
it may be multi-byte character, use DEC_POS instead.

(try_window): Change the way of calculation of tab
offset.  We now use val.tab_offset to maintain tab offset.
Removed local variable tab_offset.
(try_window_id): Likewise.

(pos_tab_offset): Return COL (Modulo is no longer valid).
Add the line to set tab_offset member.
Use pos.tab_offset.

(redisplay_window): Specify big negative number for TOHPOS
of compute_motion().
(try_window_id): Likewise.

(tri_window_id): Specify "1 << (BITS_PER_SHORT - 1)" to
express "Don't care".

move_to_column faster.
(current_column): Set current_column_bol_cache.

(Fmove_to_column): Use current_column_bol_cache.

(current_column): When the buffer may have multi-byte
characters, call current_column_1.
(compute_motion): Handle multi-byte characters.
(current_column_1): Likewise.
(Fmove_to_column): Likewise.

Include "charset.h".
(compute_motion): Remove the variable PREV_VPOS.
Introduce new local variables (multibyte, wide_column, prev_pos,
contin_hpos, prev_tab_offset) to handle multi-byte characters and
wide-column characters.

(pos_tab_offset): Specify "- (1 << (BITS_PER_SHORT - 1))"
to express big negative number (for consistency with xdisp.c).

(vmotion): Specify "1 << (BITS_PER_SHORT - 1)" to
express "Don't care".

check against truncated text at end of line.
Add giving-up for buffers with reverse direction.
(remake_frame_glyphs): Use FRAME_MESSAGE_BUF_SIZE()
instead of FRAME_WIDTH, as the message may include multi-byte
character and the length may be longer than width.
(width_run_cache_on_off): Disable width-run-cache when
multi-byte characters are enabled.
(skip_invisible): Don't put the boundary in the middle of
multibyte characters.

(direct_output_forward_char): Bug fix.  Add
XFASTINT (w->left) for losing cursor check.

Include charset.h.
