You can't do that with $read(). You can get pretty close by using $readn or $lines() and echo a <Ctrl+B> instead of a truly blank line etc, but the recommended method for what you want is /loadbuf. Not only does it echo all the blank lines and multiple spaces but is also far faster than looping through $read().
