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.
