Add option to strip surrounding paragraph element about excerpts HOT 5 CLOSED

I think the excerpt variable that the plugin creates should be an object and return excerpt.text, excerpt.html (with <p></p> stripped but all other HTML preserved). I tend to need a text version for the description meta tag and the HTML version for overview or archive pages.

from excerpts.

Returning an object might help, but this is a good use case for metalsmith-keymaster. (hope it's o.k. to plug my own plugin). e.g.

.use(excerpts())
.use(keymaster({  // remove trailing </p> from excerpt and replace with ...
      from: function(fileData) {
         var ex = fileData.excerpt || "";
         return ex.substring(0, ex.length - 4) + " ...";
      },
      to: "excerpt"
   }))

Such a feature would be great for Atom feed summaries.
