(compute_trt_identity, compute_trt_shuffle):
Set up bytes[0] with the charset code.
Check for a sub-char-table when deciding to recurse.
Terminate the loop properly for a sub-char-table.
(compute_trt_inverse): Totally rewritten.
Args are now Lisp_Object. Callers changed.
(compute_trt_identity, compute_trt_shuffle): New subroutines.
(init_casetab_once): Use XSETFASTINT to store into case table;
use CHAR_TABLE_SINGLE_BYTE_SLOTS to end the loop.
(describe_vector): Rewrite char-table handling.
(Fmake_keymap): Make a char-table.
(access_keymap, store_in_keymap): Likewise,
(describe_map, Fset_keymap_parent, Faccessible_keymaps): Likewise.
(Fwhere_is_internal, Fcopy_keymap): Handle a char-table.
(copy_keymap_1, accessible_keymaps_char_table): New subroutines.
(where_is_internal_1, where_is_internal_2): New functions.
(syms_of_keymap): Set up Qchar_table_extra_slots prop on Qkeymap.
(Fread_variable, Fread_string, Fread_from_minibuffer): Likewise.
(read_minibuf): Now static. New arg DEFALT. Callers changed.
Bind minibuffer-default here.
(read_minibuf_unwind): Now static.
(Fcompleting_read): Past DEF to Fread_from_minibuffer;
no need to use it directly here.
(Fcompleting_read): New arg DEF. Callers changed.
(Qminibuffer_default): New variable.
(syms_of_minibuf): Initialize it.
(fontset_pattern_regexp): Delete code for handling nickname of a
fonset. It is now handled in Fquery_fontset by consulting
Vfontset_alias_alist.
(Fquery_fontset): Handle Vfontset_alias_alist.
(syms_of_fontset): Terminate each line by `\n\' in doc-string of
alternate-fontname-alist. Declare Lisp valiable
fontset-alias-alist. Doc-string of highlight-wrong-size-font
and clip-large-size-font modified.
(Fdefine_charset): Doc-string modified.
(find_charset_in_str): Add 4th arg TABLE which is a character
unification table.
(Ffind_charset_region): Add optional arg TABLE which is a
character unification table.
(Ffind_charset_string): Likewise.
(Venable_character_unification,
Vstandard_character_unification_table_for_read,
Vstandard_character_unification_table_for_write,
Qcharacter_unification_table): New variables.
(syms_of_coding): Initialize and declare them.
(DECODE_ISO_CHARACTER): Modified to handle a character unification
table instead of Valternate_charset_table.
(DECODE_DESIGNATION): Delete handling of Valternate_charset_table.
(decode_coding_iso2022): Handle a character unification table.
(ENCODE_ISO_CHARACTER): New macro.
(encode_designation_at_bol): Handle a character unification table.
Do not return -1 even if end-of-line is not in the current run.
(encode_coding_iso2022): Handle a character unification table.
Call macro ENCODE_ISO_CHARACTER instead of calling
ENCODE_ISO_CHARACTER_DIMENSION1 and
ENCODE_ISO_CHARACTER_DIMENSION2 directly. Check the size of
carryover before copying it to destination.
(setup_coding_system): Initialize the member
character_unification_table of the struct coding system to Qnil.
(Fset_keyboard_coding_system): Doc string augmented.
CODING_SYSTEM. Move gap after a newline code if we are encoding
in a coding system which requires designation sequences to be put
at beginning of line. Set coding.last_block to 1 before calling
a_write for an empty file.
(build_annotations): Code tuned up for handling
pre_write_conversion of a coding system.
(e_write): Delete code for handling carryover of code conversion.
It is now handled in encode_coding.
(auto_save_1): Supply 7th new arg CODING_SYSTEM as Qnil to
Fwrite_region.
