The `verify` and `create` subcommands of the bundle builtin do not properly verify the command line arguments that have been passed in. While the `verify` subcommand accepts an arbitrary amount of ignored arguments the `create` subcommand does not complain about being passed too few arguments, resulting in a bogus call to `git rev-list`. Fix these errors by verifying that the correct amount of arguments has been passed in.
