 I don't think so.  In this syntax a newline character is a separator
 distinguished from normal white spaces by read statement.

 No, my intention is grouping multiple words by a newline.  By using
 "for", lines cannot be separated from each other in the following
 case:

foo="
	foo foo2
	bar bar2
	baz
"
