v11 looks good to me.

I intentionally didn't include this test because the code is trivial:

``
/* Skip whitespace */
if (c == ' ' || c == '\t' || c == '\n' || c == '\r')
continue;
```

And also because we never tested it for base64. If we want to start
testing it we should add tests both for base64 and base32hex which IMO
should be a separate patch.
