* pkg_resources.Distribution: Fix self arguments
* docutils: Remove spurious ellipses
* Add self argument to markupsafe.Markup.format()
While the actual signature is also "def format(*args, **kwargs)", the
implementation extracts "self" from "args" as first step.
* werkzeug: Remove methods not present during runtime
UpdateDictMixin.calls_update() and EnvironBuilder.form_property()
get deleted while constructing the respective class.
* requests: Add missing self argument
