Just actually looked at the code (a novel idea)- repo-add writes
replaces info to ./desc, which is the same behavior as pacman 2. Why
don't we assume this behavior for now (no point in changing it if it
may just get changed again), and go from there. If we want to do a DB
format change, that is a whole different issue.
