    The Request.headers dictionary is not a documented interface.  It should
    stay that way, because the complete set of headers are only accessible
    through the .get_header(), .has_header(), .header_items() interface.
    However, .headers pre-dates those methods, and so real code will be using
    the dictionary.

    The introduction in 2.4 of those methods was a mistake for the same reason:
    code that previously saw all (urllib2 user)-provided headers in .headers
    now sees only a subset (and the function interface is ugly and incomplete).
    A better change would have been to replace .headers dict with a dict
    subclass (or UserDict.DictMixin instance?)  that preserved the .headers
    interface and also provided access to the "unredirected" headers.  It's
    probably too late to fix that, though.


    Check .capitalize() case normalization:

    >>> url = "http://example.com"
    >>> Request(url, headers={"Spam-eggs": "blah"}).headers["Spam-eggs"]
    'blah'
    >>> Request(url, headers={"spam-EggS": "blah"}).headers["Spam-eggs"]

    but that could be changed in future.
