no unnecessary JavaScript 👿

You are making several assumptions for this to work: 1) images are always block-level elements, which is not necessarily true---images can be inline elements (e.g. emotion icons); 2) there is only one image on a line, which may not be true, either---there could be multiple images side by side on a line. My JS trick also requires assumptions, but I think those assumptions are more reasonable: https://yihui.org/en/2018/11/md-js-tricks/#how-to-center-images-in-paragraphs

Anyway, it is simple enough to add your own CSS to your site. You don't really need my support. Example:

• https://github.com/rbind/yihui/blob/master/layouts/partials/head_custom.html#L16
• https://github.com/rbind/yihui/blob/master/static/css/custom.css

Thanks for the feedback. I'm not concerned about upstreaming all of my changes, I just like to make useful contributions. But you are right, I should have put more thought into this.

Thanks anyway!
