The current version of POSIX is available here:
It says, in
The here-document shall be treated as a single word that begins after
the next <newline> and continues until there is a line containing only
the delimiter and a <newline>, with no <blank>s in between.
Thus I think I agree with dash here. I suggest this alternative
Foo bar baz quux.
