This is easy to do if we want it. I cannot think of a case where
de-duplicating and sorting work tree path arguments would hurt.

Per-path progress output of some commands now appears in sorted order,
which is probably for the better.

Diffs produced with 'got diff path1 path2 ...' in a work tree now
remain sorted regardless of the given order of path arguments.

ok?
