That blog post suggests putting the top-level "dotfiles" directory under version control. But doesn't it make more sense, at least with git, to put each individual subdirectory under dotfiles under in its own separate repo?

With the blog post's solution, when you want to revert to an older revision of, say, your .vim or .emacs.d dotfiles you're also going to be automatially reverting your .bash and whatever other random dotfiles you have. With the latter solution, when you revert your dotfiles/vim or dotfiles/emacs subdirectory, you only get an older revision of your vim or your emacs files.

Does that make sense?
