(Fprocess_running_child_p): New function.
(process_send_signal): If CURRENT_GROUP is `lambda'
then don't send the signal if the shell owns the terminal.
(Finterrupt_process): Doc change.
CODING_MODE_LAST_BLOCK bit is not yet set in coding->mode, set it
and try decoding again.
(Fprocess_send_eof): If the coding system of PROCESS
requires flushing, call send_process with null-string at first.
unibyte, for initializing the process coding systems.
Instead, use the normal multibyte code, but check
BUFFER's value and the default value of enable-multibyte-characters.
(Fopen_network_stream): Likewise.
Store inherit_coding_system_flag as a Lisp_Object.
(Fopen_network_stream): Likewise.
(Fprocess_inherit_coding_system_flag): Access it as Lisp_Object.
(read_process_output): Likewise.
Fprocess_inherit_coding_system_flag): New functions.
(syms_of_process): Defsubr them.
(Fstart_process, Fopen_network_stream): Initialize inherit_coding_system_flag.
(read_process_output): If the process buffer isn't dead, call
after-insert-file-set-buffer-file-coding-system.
if enable-multibyte-characters is nil. Initialize members
decoding_carryover and encoding_carryover of PROC.
(create_process): Adjusted for the change of encode_coding.
(Fopen_network_stream): Initialize members decoding_carryover and
encoding_carryover of PROC.
(read_process_output): Adjusted for the change of decode_coding.
(send_process): Adjusted for the change of encode_coding.
(read_process_output): New var `multibyte'.
Set it according to which coding system was used.
(read_process_output): Handle bytes vs chars.
(send_process): Use size_byte of OBJECT.
(Fprocess_send_string): Pass size_byte to send_process.
(Fprocess_send_region): Make bytepos for send_process.
(read_process_output): Save, restore, and update both kinds of ptrs.
(send_process): OFFSET is now in bytes.
proc_encode_coding_system[p->outfd] is NULL, instead of allocating
`struct coding_system' for encoding, just skip setting up coding
system for encoding. Set Vlast_coding_system_used after some text
is read.
(send_process): Set Vlast_coding_system_used after deciding a
coding system to be used for encoding.
for proc_decode_coding_system[channel]. It is already done in
detect_coding called via decode_coding.
(wait_reading_process_input): Call detect_input_pending
whenever read_kbd is 0, not just when wait_for_cell.
nil, set coding system for decoding output of process to
emacs-mule, and set coding system for encoding to nil.
(Fopen_network_stream): If enable-multibyte-characters is nil, set
coding systems for decoding and encoding to nil.
