(Qprint_escape_nonascii): New variables.
(syms_of_print): Initialize them and set up Lisp variable.
(PRINTPREPARE): Bind print-escape-multibyte to t if appropriate.
Also bind print-escape-nonascii if appropriate.
(print): Test print_escape_multibyte and print_escape_nonascii,
rather than enable-multibyte-characters.

inserting in a unibyte buffer.

in multibyte case, before calling strout.

(print) <Lisp_String>: Use it to force printing single-byte
non-ASCII characters as octal escapes.
(syms_of_print): Define print-escape-nonascii.

multibyte characters.
(print): Likewise.

(printchar, strout): If echo area text converted to multibyte
does not all fit, truncate it at char boundary.

visited file, undo list, etc.

for struct Lisp_Buffer_Local_Value.

update message_enable_multibyte, and convert previous text
from unibyte to multibyte if necessary.

`unsigned char' to handle multibyte character code.

single-byte non-ASCII chars using octal escapes.

(print): When multibyte is disabled,
print multibyte string chars using hex escapes.

(printchar): Pass new arg to message_dolog.
(strout): New arg MULTIBYTE.  Callers changed.

(strout): Take args SIZE and SIZE_BYTE;
operate on both chars and bytes.
(print_string): Pass new arg to strout.
If not using strout, fetch a whole multibyte char at once.
(write_string): Pass new arg to strout.
(write_string_1): Likewise.
(print) <case Lisp_String>: Scan by chars and bytes.
(print) <case Lisp_Symbol>: Scan name by chars and bytes.

(PRINTPREPARE): Use make_multibyte_string.
Initialize print_buffer_pos_byte.  Use insert_1_both.
(printchar): Update print_buffer_pos_byte and print_buffer_pos.
(print_buffer_pos_byte): New variable.

(PRINTPREPARE): For a marker, set old_point_byte and start_point_byte.
Set both kinds of PT from the marker.
(PRINTFINISH): For a marker, use set_marker_both.
Restore both kinds of PT.
(print): For strings and symbols, handle multibyte chars.

Don't declare arg type taken by 2nd arg.

(internal_with_output_to_temp_buffer): Protoype parameter
FUNCTION.
(Ferror_message_string): Remove extra argument of
print_error_message.
(write_string): Define as returning nothing.
(write_string_1): Likewise.
(print_error_message): Likewise.

Define to work around hpux 7 <math.h> problem.
(<math.h>): Include.
(<float.h>, <stdlib.h>): Include if STDC_HEADERS.
(FLT_RADIX, DBL_MANT_DIG, DBL_DIG): Default to IEEE values.
(DOUBLE_DIGITS_BOUND): New macro.
(float_to_string): By default, generate the fewest number of digits
that represent the floating point value exactly.

(Vprint_gensym): Now a Lisp_Object; Renamed from print_gensym.
(syms_of_print): Set up both as Lisp vars.
(PRINTPREPARE, PRINTFINISH): Don't clear Vprint_gensym_alist
if Vprint_gensym is a cons cell.

(printchar, strout): Handle multibyte characters.
(print): Correct the value of size_in_chars of a bool vector.
