Merge from vendor branch TNF:
Importing ruby-rdoc version 3.6.1.

This is newer version of rdoc which bundled with ruby18-base/ruby19-base.
It is expected to use instead of those bundled version since some ruby
packages require newer version of rdoc command (especially ruby18-base).

RDoc produces HTML and command-line documentation for Ruby projects.  RDoc
includes the +rdoc+ and +ri+ tools for generating and displaying online
documentation.
