Bug #3084: ri shows the same description twice
http://redmine.ruby-lang.org/issues/show/3084

ruby -v: 1.9.2dev (2010-04-03 trunk 27196) [i686-linux]

For some classes/modules, ri shows the same description twice. e.g.:

  $ ruby -v
  ruby 1.9.2dev (2010-04-03 trunk 27196) [i686-linux]
  $ ri RDoc
  = RDoc
  
  (from ruby core)
  ----------------------------------------------------
  = RDoc - Ruby Documentation System
  
  This package contains RDoc and ...
    ... document continues ...
  merchantibility and fitness for a particular purpose.
  = RDoc - Ruby Documentation System   # I've already seen this!
  
  This package contains RDoc and ...

The classes with this problem: Array, Hash, Time...
It seems like this only happens for the core classes, since I haven't found
any of the gem-installed classes suffering from this.
