A couple weeks ago, Lars removed "The" from a bunch of info nodes.
Now `C-c C-i' is throwing an error because of it.

Signaling: (error "No such node: The Summary Buffer")
  signal(error ("No such node: The Summary Buffer"))
  cerror("No such node: %s" "The Summary Buffer")
  apply(cerror "No such node: %s" "The Summary Buffer")
  error("No such node: %s" "The Summary Buffer")

A quick glance at gnus.el shows there are just two instances that need
to be fixed, but I could have missed others if they occur elsewhere.
