So there is no substitute for pcvs.el and psvn.el now – why is the
family
of vc-*.el files then autoloaded?
Why not? It does provide useful functionality via
C-x v =, C-x v ~, C-x v l, and C-x v g
as well as information in the Modeline about the fact that the file
is under
version control and which system is used.
These are very useful in my experience and completely orthogonal to
what
pcvs or psvn provides (which I obviously find very useful as well).
Just don't expect VC to provide a full frontend (at least not yet).
