Fix tab size for Emacs users.
Fix tab size for Emacs users.

For some reason .dir-locals.el was setting tab-width to 2.  That's a Really
Bad Idea, because if somehow (as happened in my case) indent-tabs-mode was
't instead of nil like it should have been, Emacs will insert tabs instead
of spaces, and it'll *look* like it's doing the right thing.
