Issue 14709: http.client fails sending read()able Object

It seems that http.client's send() function lacks an else/return statement in Line 772.
If this method is called with an read()able Object, it jumps into 

L 750: if hasattr( data,"read"):

processes this data correctly, but then falls through (due to missing else ) to

L 773: try:
L 774:     self.socket.sendall(data)

where finally an TypeError raises.
