use vc-find-root instead of vc-got-root I'm not entirely sure, but I don't want to cause cyclic dependencies between vc-got and vc-got-stage (even thought they depend on each others).

adding vc-got-stage vc-got-stage is a minor mode for vc-diff buffers controlled by Got. It's a tentative at implementing the stage operation for specific changes instead of whole files. vc.el works with filesets, and this is fine. But sometimes you want to commit only certain hunks. This initial implementation allows the user to stage changes, but you can't commit them (yet).
