[ID 20000418.001] open bug

If the first characters of an open filename specification are whitespace,
the open fails without yielding a failure status.  As I understand the first
two sentences of the 2nd paragraph on page 191 of the camel book, this
should not be the case.  Here's a small program to illustrate the problem:

	#!/usr/bin/perl -w
	#Illustrates a perl bug
	#According to the second paragraph on page 191 of the bible, leading
	#whitespace should not be a problem.  Here it is shown to be.

	open OUTPUT, "  | cat "  ||  die;
	print OUTPUT "THIS LINE DOES NOT APPEAR\n";
	close OUTPUT;

	open OUTPUT, "| cat "  ||  die;
	print OUTPUT "THIS LINE DOES     APPEAR\n";
	close OUTPUT;

	exit 0;

Running this program yields (for me):

	print on closed filehandle main::OUTPUT at pt.pl line 7.
	THIS LINE DOES     APPEAR

Here's the output of my 'perl -V':
