(syms_of_fns): Initialize new variables.
(sweep_weak_table): Handle weakness `key-or-value' and
`key-and-value'.
(Fmake_hash_table): Recognize `key-and-value' and `key-or-value'
weakness, with t meaning the same as `key-and-value'.
(Qsafe_chars, Vchar_coding_system_table, Qchar_coding_system): New
variables.
(coding_safe_chars): New function.
(CODING_SAFE_CHAR_P): New macro.
(CHARSET_OK): New arg C. Call CODING_SAFE_CHAR_P instead of
checking safe_charsets member of the coding system. Caller
changed.
(detect_coding_iso2022): New local variable safe_chars.
(DECODE_DESIGNATION): Call CODING_SAFE_CHAR_P instead of checking
safe_charsets member of the coding system.
(decode_coding_iso2022): New local variable safe_chars.
(ENCODE_ISO_CHARACTER_DIMENSION1): Don't check unsafe chars here.
(ENCODE_ISO_CHARACTER_DIMENSION2): Likewise.
(ENCODE_ISO_CHARACTER): Arguments changed. Caller changed.
(ENCODE_UNSAFE_CHARACTER): New macro.
(encode_coding_iso2022): New local variable safe_chars. Check
unsafe chars.
(setup_coding_system): Delete the code to initialize
coding->safe_charses
(intersection, find_safe_codings): New functions.
(Ffind_coding_systems_region_internal): New function.
(syms_of_coding): Defsubr it. Initialize Qsafe_chars,
Qsafe_cding_system. Make Vchar_coding_system_table a Lisp
variable and initialize it.
(HAVE_SYS_WAIT_H): Undef for HPUX7, Convex.
[!HAVE_SYS_WAIT_H]: Define things unconditionally. More
perspicuous definitions.
(WTERMSIG): Fix bit pattern used.
(Fconstrain_to_field): Add the INHIBIT-CAPTURE-PROPERTY argument.
Use scan_buffer instead of find_before_next_newline, because it
allows us to detect the boundary case where there's a newline at
the search limit.
(Qboundary): New variables.
(syms_of_editfns): Initialize Qboundary.
parameters instead of using int parameters. Expect FN to accept
EMACS_INT parameters.
(display_echo_area, resize_echo_area_axactly, current_message)
(truncate_echo_area, set_message_1): Call with_echo_area_buffer
with new argument list.
(resize_mini_window_1): New callback function.
(current_message_1, truncate_message_1, set_message_1): Change
parameter lists to the new format expected by
with_echo_area_buffer.
