#15 Diff between commit and staging

[Hakon]

I frequently need to view the diff between a git commit (HEAD or master) and staging/working directory. Is this something that can be added to diffuse? The extension to other VCS seems straight forward, although I only ever use Mercuial besides git.

See attachment for a patch against r440 for a proposal. Until this or something similar is in trunk, I have taken the liberty of cloning this repo on GitHub (hakonhall/diffuse).

Cheers, Håkon
