Summary: urllib2: improper capitalization of headers

Initial Comment:
urllib2.py version 1.72 uses capitalize() on HTTP
header names. This results in headers like "User-agent"
instead of "User-Agent". This causes HTTP 400 errors on
some servers when the request has a body, because there
are two content length headers placed in the request:

"Content-Length" (inserted by httplib)
"Content-length" (inserted by
Request.add_unredirected_header)

The capitalization is incorrect, and httplib inserts
Content-Length anyway, so I'm not sure why urllib2 is
bothering.
