Prevent completion after parenthesis

I want SuperTab don't complete after all parenthesis: `[, ], (, ), {, }`

This doesn't help:

```vim
let g:SuperTabNoCompleteAfter = ['^', '\s', '"', "'", ',', '.', ':', '[', ']', '(', ')', '{', '}']
```

This too:

```vim
let g:SuperTabNoCompleteAfter = ['^', '\s', '"', "'", ',', '.', ':', '\[', '\]', '\(', '\)', '\{', '\}']
```
