[issue20911] urllib 'headers' is not a well defined data type

[R. David Murray]

New submission from R. David Murray:

Some places in the code it is an email.message.Message object.  Some places it is a simple dictionary.  In one place (FTP), it is a string with embedded newlines.

I'm not sure what should be done about this situation, but it looks like a bug magnet, and it makes it pretty much impossible to document the data type.
