(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.
Save value of x_catch_errors and pass to x_uncatch_errors.
(x_catch_errors): Use specpdl so can be nested.
Use a Lisp string to as the buffer for the X message.
(x_uncatch_errors, x_had_errors_p, x_check_errors): Related changes.
(x_catch_errors_unwind): New function.
(x_error_quitter): Call x_error_catcher if appropriate.
(x_error_message_string): New variable.
(syms_of_xterm): Defvar it.
(x_caught_error_message): Variable deleted.
(X_ERROR_MESSAGE_SIZE): Renamed from X_CAUGHT_ERROR_MESSAGE_SIZE.
(x_error_handler): New function, calls x_error_quitter or ..._checker.
(x_initialize): Use x_error_handler as error handler for X.
