Note Submitter: sgbeal at googlemail dot com ---- The docs say: "Heredoc text behaves just like a double-quoted string, without the double quotes" but there is a notable hidden exception to that rule: the final newline in the string (the one before closing heredoc token) is elided. i.e. if you have: $foo = <<<EOF a b c EOF; the result is equivalent to "a\nb\nc", NOT "a\nb\nc\n" like the docs imply.
