3# It may be argued that
4#   x=$(cat <<EOF
5#   foo
6#   EOF)
7# is a valid complete command that sets x to foo, because
8#   cat <<EOF
9#   foo
10#   EOF
11# is a valid script even without the final newline.
12# However, if the here-document is not within a new-style command substitution
13# or there are other constructs nested inside the command substitution that
14# need terminators, the delimiter at the start of a line followed by a close
15# parenthesis is clearly a literal part of the here-document.

17# This file contains tests that also work with simplistic $(...) parsers.
