Title: Broken markdown file extension regexp (regression of #1382)

Hello!

On the last edition of the the regexp that matches markdown file extensions, the part that matches the beginning of the file extension of removed. I was setting up a site with some [Rmarkdown](http://rmarkdown.rstudio.com/) files, and `.Rmd` files were being processed as regular markdown files. Patched!

I specifically used `.Rmd` in the test. I hope that is ok! I used this fix with an [Rmarkdown converter](https://github.com/atbradley/jekyll-rmarkdown), and it worked fine (but out of scope of this PR).

Cheers!
