Speaking of messy directories under VC, is there any way instead of
writing those files to disk they could be loaded directly into a buffer
so as not to clutter the checkout? Perhaps they could be checked out
into a temporary file first?

If this option doesn't currently exist in VC, how difficult would it be
to add?
