loop-nav: should .previous be .prev?

[lkraav]

This is to eliminate the difference with paginate_links()

AFAiCS theme's navigation class should follow core naming, so we don't have to chase this in styling. Am I missing anything significant with this reasoning?

Core naming doesn't really matter in this instance. .previous is more consistent with my other themes. Plus, core isn't even consistent with this naming and doesn't always use the class:

I've got some Hybrid Core filters I plan on adding for cleaning some of this stuff up though.
