Really minor enhancement I think.

So I have decided Hyperscript is a good idea. Upon using it with html-node, it actually works great, except the html generated keeps newlines, useless space characters, and I suppose tabs if I was using them. Ultimately, my html is tidy when it is sent off by the server, except for the formatting I've entered in the attribute string.

This isn't a particularly huge deal. A few spaces never killed anyone. It's more like I see it and my brain says no.

Attributes have not had formatted code placed into them in the past, so this wasn't really a thing.

So something like this:

<button _="on click set :dialog to the closest <dialog/>
           then set :video to the next <video/>
           then repeat in :video.srcObject.getTracks()
               call it.stop()
           end
           then send reset to the next <canvas/>
           then call :dialog.close()">

That will be sent over the wire with the formatting.

impl Display for Element {
    /// Format as an HTML element.
    fn fmt(&self, f: &mut Formatter<'_>) -> fmt::Result {
        write!(f, "<{}", self.name)?;

        for (key, value) in &self.attributes {
            write!(f, " {key}")?;

            if let Some(value) = value {
                let encoded_value = html_escape::encode_double_quoted_attribute(value);
                write!(f, r#"="{encoded_value}""#)?;
            }
        }
        write!(f, ">")?;

        if let Some(children) = &self.children {
            write_children(f, children, false)?;

            write!(f, "</{}>", self.name)?;
        };

        Ok(())
    }
}

Looks like this piece of code here one could just add something which removes this type of whitespace from the value variable before passing it to encode_double_quoted_attribute. Specifically, replace all newlines + zero or more spaces + zero or more tabs with one space. Something like that. That assumes I'm even looking in the right spot.

I'm willing to implement this myself. Feedback?
