Replace reference from vinum.8 to gvinum.8, it was advised in the PR to replace this with vinum.4, but that's the kernel interface manual, which is not appropriate in my understanding. I think that gvinum is a suitable replacement for this. PR: docs/121938 Submitted by: "Federico" <federicogalvezdurand at yahoo dot com> MFC after: 3 days
