Summary: [rdoc] constants with multiline values

Initial Comment:
RDoc as of ruby 1.8.6 does not correctly handle constants whose value extends beyond the first line.

Originally reported and patched by Chris Alfeld in

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/7647

The original post noted the following example:

    ----
    A = [
     1,
     2,
     3
    ]

    B = {
      1 => 'foo',
      2 => 'bar'
    }

    C = proc do |x|
      x+1
    end
    ----


The original patch was against 1.8.4. The patch for 1.8.6 is:
