A 'git init' wouldn't exactly hurt, though.

I like this suggestion better (no "special" files), but would we be able 
to avoid scope creep? Wouldn't users then expect being able to specify 
ignored directories in such projects? And then faster indexing (e.g. 
using caching), compared to the VC backend?

Projectile uses the "special file" for the former, and I'm not really 
fond of its solution for the latter.
