    Use a longer message to explain en passant captures
    
    This reverts 73a3af2e. There's no longer any need to use a short
    message, since we will now always put it in the info bar.
    
    Let's also italicize the text, as is appropriate. Sadly this means
    translators will have to work with markup, because they may need to
    remove the markup, or reorder the string, so it requires violating the
    normal guidance to avoid markup in translatable strings. That's probably
    fine; we should avoid it wherever possible, but not when it's really
    needed.
