vc wish: walk through diffs

[Lars Magne Ingebrigtsen]

One thing I've wanted to have for years is a way to "walk through" the
changesets the current file is part of.

Say I'm in a buffer.  I hit (er) `C-x v p' to get the previous changeset
that was applied to this file.  Then I hit `M-p' to go to the one before
that, and so on.

I know nothing of the vc internals.  Is this doable to implement?
