Supports: git, svn, hg
Generate a Differential diff or revision from local changes.
Under git, you can specify a commit (like __HEAD^^^__ or __master__)
and Differential will generate a diff against the merge base of that
commit and HEAD.
Under svn, you can choose to include only some of the modified files
in the working copy in the diff by specifying their paths. If you
omit paths, all changes are included in the diff.
