Issue 4141: More fixes for tag_wranglings page

https://code.google.com/p/otwarchive/issues/detail?id=4141
The word "email" should go back inside the `<a>` on all three of these links to make what they're for clearer to anyone using a screen reader. I'd also suggest removing the space between "mailto:" and the email address itself. It will _probably_ work with the space (I checked in Safari), but without the space is standard, so there's less uncertainty there.
