Variable line-break spacing in Vimeo descriptions not being detected

[spongbros]

As seen in the description of https://vimeo.com/38644453, Vimeo appears to allow different amounts of spacing between paragraphs and line-breaks. (Some sentences have a larger vertical gap between the lines.) Looking at the source, a combination of <p> and <br> HTML tags are used to achieve this effect. These are not detected by youtube-dl’s --write-description setting and are rendered only as regular line breaks. The .info.json file uses /n at the end of each line. Could there be a way to detect presentation and formatting elements of the description and an option to preserve them in the .description file? If necessary, descriptions with formatting could be saved in an HTML, XML or RTF format depending on which one is felt to be most suited.

What follows is the output of youtube-dl https://vimeo.com/38644453 -v. I’m using the latest Homebrew build.
