From: Orgad Shaneh <orgads@xxxxxxxxx> The argv argument of collect_changed_submodules() contains obly object ids (the objects references of all the refs). Notify setup_revisions() that the input is not filenames by passing assume_dashdash, so it can avoid redundant stat for each ref. A better improvement would be to pass oid_array instead of stringified argv, but that will require a larger change, which can be done later.
