idea: blame-deps (aka 3D-blame)

The idea is to do something like

git deps some-file.txt

This will open the git-deps browser with the contents of the file loaded into a pane in a typical blame view:

e5392d87  1) This is some file.
e5392d87  2) =====================================
e5392d87  3)
69d951f2  4) Look at all the nice contents.
e5392d87  5)

The magical thing is that each of the revisions are clickable - doing so will open the git-deps graph for the clicked commit.
