From 6d99caa5ee7502dcb61f1154f54f527ec7ed4f2d Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Sat, 3 Mar 2001 19:31:37 +0000
Subject: (die): New function. (create_temp_file, xfopen, xfclose, write_bytes,
 sort_buffer_size, fillbuf, main): Use it to regularize error messages.  The
 only change in behavior is that write_bytes and the final close used to say
 "write error" but now give just the output file name, which should be enough.
