Subject:      grep-2.0b: close stdout and make sure it succeeds

Hi Alain,

Thanks for taking up the reins!

Almost every program that writes a single byte to stdout should
do the following just before exiting: close stdout and give a
diagnostic if the close fails.

Otherwise, write errors can go unreported.  You can provoke this
by e.g. making grep generate lots of output and redirect that output
to a floppy or to any file system that's nearly full.

GNU hello should set a good example and do this, too.

Here's a patch I've been using for a long time:

        * src/grep.c: Cause grep to fail if `fclose (stdout)' fails.

+  if (fclose (stdout) == EOF)
+    error (_("writing output", errno));

   exit(errseen ? 2 : status);
 }
