According to the typeshed, the scheme argument to urlparse is Optional. However, with this change, a value of None will result in an error like:

AttributeError: 'NoneType' object has no attribute 'replace'

I'm not sure whether the typeshed is wrong or if this line should be guarded with if scheme is not None, but we should definitely fix one or the other and perhaps improve the documentation on this option.

Thanks to @branchvincent for doing the digging and reporting this issue to me.
