I don't think it's a good idea to rename "new" to "init".

Firstly, I don't see why "init" describes creation of a new repository better than "new".

Secondly, "new" is actually different from "init" in Git or Mercurial, because it creates an SQLite file for repository, not a dot-folder inside the specified directory, so renaming it to "init" can be misleading. Also, it requires a name of the repository file, not directory.
