Block comments unindent by one space each line

Seems like multiline comments might confuse vim-solidity. Having said that, I am using editorconfig, so if you can't reproduce, that might be where we diverge :)

```
contract SimpleStorage {
    uint storedData;

    /** 
    *
   *
  *
 *
    */
    function set(uint x) {
        storedData = x;
    }  
```
