[PATCH] printing multiple heredocs in list

[Grisha Levit]

If there are multiple commands in a row that each require printing the
connector prior to the heredoc body, the connector ends up in the wrong
place for commands after the first:

fun() {
cat <<EOF &&
EOF
cat <<EOF &&
EOF
cat <<EOF
EOF
}
declare -f fun

fun ()
{
    cat <<EOF &&
EOF
 cat <<EOF
EOF
 && cat <<EOF
EOF

}

This fix worked for every test case I could think of but I can't say
I'm groking all the printing logic yet.
