The proposed vc-ediff works when visiting any version-controlled file.

What if I don't visit a version-controlled file, and still want to
compare some file against some of its versions?

I would visit the file I want to compare first and then invoke vc-ediff. To me, that's not much different than calling a version of vc-ediff, which asks me first which file to compare, like ediff-revision does.

However, if this is really a desired feature, we could enhance vc-deduce-fileset to not just fail with `no fileset found' on being invoked on a buffer that is not version controlled, but ask for a file. This would then also work for vc-diff and keep everything consistent.
