Remove special logic that closes HTTPConnection socket on EPIPE.
http://bugs.python.org/issue5542
If the socket is closed, the client has no chance to read the response
from the server. EPIPE means that it isn't possible to write more
data from the socket, but not that it is impossible to read.
Also, various formatting changes.
