[docs] Typo in urllib2 docs

[Dmitry Chaplinsky]

http://docs.python.org/2/library/urllib2.html

This function returns a file-like object with *two* additional methods:

   - geturl() — return the URL of the resource retrieved, commonly used to
   determine if a redirect was followed
   - info() — return the meta-information of the page, such as headers, in
   the form of an
mimetools.Message<http://docs.python.org/2/library/mimetools.html#mimetools.Message>instance
(see Quick
   Reference to HTTP Headers <http://www.cs.tut.fi/%7Ejkorpela/http.html>)
   - getcode() — return the HTTP status code of the response.

docs says about two methods but 3 are listed.

WBR, Dmitry
