parser: Fix alias expansion after heredoc or newlines
This script should print OK:
alias a="case x in " b=x
a
b) echo BAD;; esac
alias BEGIN={ END=}
BEGIN
cat <<- EOF > /dev/null
$(:)
EOF
END
: <<- EOF &&
$(:)
EOF
BEGIN
echo OK
END
However, because the value of checkkwd is either zeroed when it
shouldn't, or isn't zeroed when it should, dash currently gets
it wrong in every case.
This patch fixes it by saving checkkwd and zeroing it where needed.
