namespaces: update documentation and code indentation

The previous patch changed just the functionality, while this patch focuses on
the documentation and indentation to keep review simple.

-    provides an interface to register a generic many-to-many mapping between
-    some (namespaced) names and nodes. The goal here is to control the
-    pollution of jamming things into tags or bookmarks (in extension-land) and
-    to simplify internal bits of mercurial: log output, tab completion, etc.
-
-    More precisely, we define a list of names (the namespace), a mapping of
-    names to nodes, and a mapping from nodes to names. Each mapping
-    returns a list of nodes.
+    """provides an interface to register and operate on multiple namespaces. See
+    the namespace class below for details on the namespace object.
 
-    Furthermore, each name mapping will be passed a name to lookup which might
-    not be in its domain. In this case, each method should return an empty list
-    and not raise an error.
-
-    We'll have a dictionary '_names' where each key is a namespace and
-    its value is a dictionary of functions:
-      'templatename': name to use for templating (usually the singular form
-                      of the plural namespace name)
-      'namemap': function that takes a name and returns a list of nodes
-      'nodemap': function that takes a node and returns a list of names
