git/diff: show each file once (thanks Igor Boehm) git/diff listed all files changed in tree, as well as any files changed compared to the branch being diffed against; this could lead to duplicates in the list of changed files. This change sorts and uniqs them, which both gives a stable order and removes duplicates.
