[PATCH v1] annotate: skip checking working tree if a revision is provided

[Edmundo Carmona Antoranz <eantoranz@gmail.com>]

If a file has been deleted/renamed, annotate refuses to work
because the file does not exist on the working tree anymore
(even if the path provided does match a blob on said revision).
