Empty contract bodies break ContractOrLibraryStatement parsing

[cgewecke]

zeppelin-solidity now has an empty bodied contract that looks like this:

pragma solidity ^0.4.8;

import "./HasNoEther.sol";
import "./HasNoTokens.sol";
import "./HasNoContracts.sol";

contract NoOwner is HasNoEther, HasNoTokens, HasNoContracts {
}

which breaks parse.js here .

Fix for this and a coverage unit test for the case are pushed to truffle3 branch in this commit

[area]

Fixed in solidity-coverage, I believe.
