handle_revision_arg: simplify commit reference lookups
The "dotdot" range parser avoids calling lookup_commit_reference() if we are directly fed two commits. But its casts are unnecessarily complex; that function will just return a commit we pass into it. Just calling the function all the time is much simpler, and doesn't do any significant extra work (the object is already parsed, and deref_tag() on a non-tag is a noop; we do incur one extra lookup_object() call, but that's fairly trivial).
