to put text into clipboard, return 1, as Fw16_set_clipboard_data
expects. In case of other failures, return 3.
(system_error_msg): New error message.
(Fw16_set_clipboard_data): If set_clipboard_data returns 3, print
system_error_msg.
off other appearances in case TS_exit_attribute_mode is not equal
to TS_end_standout_mode.
(insert_glyphs): Turn inverse video on/off for each run of glyphs
with the same face.
(turn_off_face): Reset standout_mode only if
TS_exit_attribute_mode has been output and TS_exit_attribute_mode
is equal to TS_end_standout_mode.
(conversion_buffer, conversion_buffer_size): Variables deleted.
(get_conversion_buffer): Function deleted.
(struct conversion_buffer): New structure.
(MAX_ALLOCA): New macro.
(allocate_conversion_buffer): New macro.
(extend_conversion_buffer, free_conversion_buffer): New functions.
(ccl_coding_driver): Set coding->result.
(decode_coding): Set coding->result to CODING_FINISH_NORMAL if
this is the last block of source.
(encode_coding): Likewise. Handle the source block as the last
one only when the whole source text is consumed.
(decode_coding_string): Handle the case that the output buffer is
too small to decode the whole source text. Use
allocate_conversion_buffer, extend_conversion_buffer and
free_conversion_buffer, not get_conversion_buffer.
(encode_coding_string): Likewise.
(init_coding): Function deleted.
(init_coding_once): Delete code to initialize
conversion_buffer_size.
(XTread_socket): Work around a bug of XmbLookupString. If the
input is from XIM, decode it according to the current locale. In
that case, generate multibyte_char_keystroke events.
(TRACE_MOVE) [GLYPH_DEBUG]: New macro.
(move_it_in_display_line_to): Record iterator's ascent and descent
before producing glyphs, and restore them when we know the glyph
doesn't fit on the line.
(move_it_to): Restructured so that it's easier to debug. If
moving to a vpos, and not moving to an x or character position,
stop as soon as the specified vpos is reached; don't move further
into that line because that might change the computed line height.
(try_cursor_movement): New function, extracted from the cursor
movement branch of redisplay_window. If ending on a partially
visible line, don't try to scroll if the cursor line is taller
than the window.
(redisplay_window): Use try_cursor_movement.
