Modified copy of setbuf.c to support setlinebuf function
defined as part of BSD.

FUNCTION
<<setlinebuf>>---specify line buffering for a file or stream
 
INDEX
	setlinebuf
 
ANSI_SYNOPSIS
	#include <stdio.h>
	void setlinebuf(FILE *<[fp]>);
 
TRAD_SYNOPSIS
	#include <stdio.h>
	void setlinebuf(<[fp]>)
	FILE *<[fp]>;
 
DESCRIPTION
<<setlinebuf>> specifies that output to the file or stream identified by
<[fp]> should be line buffered.  This causes the file or stream to pass
on output to the host system at every newline, as well as when the
buffer is full, or when an input operation intervenes.
 
WARNINGS
You may only use <<setlinebuf>> before performing any file operation
other than opening the file.
 
RETURNS
<<setlinebuf>> returns as per setvbuf.
 
PORTABILITY
This function comes from BSD not ANSI or POSIX.
 
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
