        * xterm.c (XTread_socket): At the beginning of the loop, pass the

        and Qunspecified_bg for foreground and background colors.

        * xterm.c (x_clip_to_row): Subtract 1 from clip width if we
        have to draw a vertical border.

        * window.c (window_scroll_pixel_based): When scrolling down by

        the case continuation lines are involved.

        (move_iterator_to): If to_y specified, always first move to x = 0,

        over.
        (move_iterator_via_matrix): Look for it->pos in the matrix, and
        calculate it->vpos and it->current_y relative to this row.
        (move_iterator_via_matrix): Set in #if 0.  It doesn't seem to
        have a big effect and it is complex.
        (move_iterator_to): Call to move_iterator_via_matrix in #if 0.

        * xfns.c (x-list-fonts): Copied from x-list-fonts.c; #include

        * x-list-font.c (Fx_list_fonts): Check INTEGERP or FLOATP for

        of section names.
        (copy_executable_and_dump_data_section): Renamed
        copy_executable_and_dump_data.  Completely rewritten to copy
        executable section by section, so that raw data areas can be
        expanded to hold dumped data as necessary.  Allows for bss data to
        be in same section as initialized data.  Reduces size of static
        heap section to that used during preload.
        (dump_bss_and_heap):
        (w32_fatal_reload_error):
        (read_in_bss):
        (map_in_heap): Obsolete functions removed.

        virtual allocation unit.  Modified to match other changes.

        * editfns.c (Fposition_bytes): If the arg POSITION is out of
        range, return nil.
        (Fbyte_to_position): If the arg BYTEPOS is out of range, return
        nil.

        * data.c (Faset): Use macro CHAR_BYTES instead of Fchar_bytes.
        * fns.c (concat): Likewise.
        * insdel.c (count_size_as_multibyte): Likewise.
        * xdisp.c (message_dolog): Likewise.

1998-08-27  Kenichi Handa  <handa@etl.go.jp>

        * coding.c (detect_coding_iso2022): Handle ESC N and ESC O
        correctly.  They are for SS2 and SS3 respectively.
        (ccl_coding_driver): Fix previous change.

1998-08-26  Paul Eggert  <eggert@twinsun.com>

        * xterm.c (fixup_locale): New function.  For now, it resets
        LC_TIME to "C" (reverting the 1998-08-07 change), and also
        resets LC_MESSAGES to "C".
        (x_term_init): Use it to fix up the locale after setlocale (LC_ALL, "").

1998-08-26  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>

        * xterm.c (x_calc_absolute_position): Cast argument to XFree, in
        case it was prototyped the old way.

1998-08-25  Kenichi Handa  <handa@etl.go.jp>

        * xterm.c (x_list_fonts): Work-around for the case XGetAtomName
        returns a null string.  This happens when dxpc 3.7 is being used.

1998-08-24  Andreas Schwab  <schwab@delysid.gnu.org>

        * keyboard.c (input-method-previous-message): Doc fix.

        * coding.c (file-coding-system-alist)
        (select-safe-coding-system-function): Doc fix.

1998-08-23  Kenichi HANDA  <handa@etl.go.jp>

        * coding.c (detect_coding_iso2022): Don't check the byte length of
        succeeding codes (0xa0..0xFF) if the codes follows single shift
        code (SS2 or SS3).

1998-08-21  Ken'ichi Handa  <handa@delysid.gnu.org>

        * coding.c (detect_coding_system): If detect_eol_type returns
        CODING_EOL_INCONSISTENT, set eol_type to CODING_EOL_UNDECIDED
        correctly.
