Actually this (the empty delim) only works with dash by accident.
I've tried bash and pdksh and they both terminate on the first
empty line which is what you would expect rather than EOF.  The
real Korn shell does something completely different.

I've fixed this in dash to conform to bash/pdksh.

OK I agree.  The reason it was there is because the parser would
have already replaced the dollar sign by an internal representation.

I've fixed it properly with this patch.

Test case:

	cat <<- $a
		OK
	$a

	cat <<- ""
		OK

	echo OK

Old result:

	dash: Syntax error: Illegal eof marker for << redirection
	OK

	echo OK

New result:

	OK
	OK
	OK
