I always thought that the terminator word must be the only thing on the
line.

The folloing shows that (d)ash does not consider EOF) to be a terminator
word because of the appended ")".

foo=$(cat <<EOF
Foo bar baz quux.
EOF)

EOF
)
echo $foo

So just use:
EOF
)

which works everywhere (and yes, I know that doesn't quite answer you actual
questin :))
