raw-text-unix.
(Fdetect_coding_region): Do not select no-conversion even if EOL
format of raw-text file is inconsistent.
(syms_of_coding): Initialize and staticpro them.
(coding_category_name): Include "coding-category-raw-test".
(setup_coding_system): Handle coding_type_raw_text.
(detect_coding_mask): Include CODING_CATEGORY_MASK_RAW_TEXT in the
return value instead of CODING_CATEGORY_MASK_BINARY.
(detect_coding): Do not check the case that `mask' is 0, which
never happens now.
(detect_eol_type): If EOL format is inconsistent, return
CODING_EOL_INCONSISTENT.
(detect_eol): If EOL format of raw-text file is inconsistent,
detect it as no-conversion.
(decode_coding): Handle coding_type_raw_text.
(encode_coding): Likewise.
(Fdetect_coding_region): Ajusted for the above changes.
(shrink_conversion_area): Handle coding_type_raw_text.
(CODING_EOL_INCONSISTENT): New macro.
(CODING_REQUIRE_NO_CONVERSION): Check also coding_type_raw_text.
(CODING_MAY_REQUIRE_NO_CONVERSION): Likewise.
(CODING_CATEGORY_IDX_RAW_TEXT): New macro.
(CODING_CATEGORY_MASK_RAW_TEXT): New macro.
(Fcall_interactively): Call Fcompleting_read,
Fread_from_minibuffer, and Fread_string with a proper value for
the arg INHERIT-INPUT-METHOD. Handle the code letter `M'.
variables.
(syms_of_minibuf): Intern and staticpro them.
(read_minibuf): New argument INHERIT_INPUT_METHOD. If it is
nonzero, remember the current input method in INPUT_METHOD, and
activate it after switching to the minibuffer.
(Fread_from_minibuffer): New argument INHERIT_INPUT_METHOD.
(Fread_minibuffer): Call read_minibuf with INHERIT_INPUT_METHOD
nil.
(Fread_string): New argument INHERIT_INPUT_METHOD.
(Fread_no_blanks_input): Likewise.
(Fread_command): Call Fcompleting_read with INHERIT_INPUT_METHOD
nil.
(Fread_function, Fread_variable, Fread_buffer): Likewise
(Fcompleting_read): New argument INHERIT_INPUT_METHOD.
(Finsert_file_contents): Decide coding system after opening a
file. Call functions set in Vauto_file_coding_system_function.
(syms_of_fileio): Declare auto-file-coding-system as a Lisp
variable.
