The intent of the patch below is to improve the coverage of the rdoc
output produced by make install-doc.  It was created with this file
(.fix.doc.rb):

<quote>
#!/usr/local/bin/ruby -w

$documents = []
$files = []
$debug = false

open(".document", "r") do |f|
  while not f.eof?
    line = f.readline
    puts "line is #{line}" if $debug
    next if line =~ /^\s*(?:#.*)?$/
    $documents << line.chomp
  end
end

$files += %x{ls}.split(/\n/)

puts "documents is #{$documents.inspect}" if $debug
puts "files is #{$files.inspect}" if $debug
$files.each do |file|
  puts file unless $documents.include?(file)
end
<quote>

and by sorting the results into .document.  This is a patch against the 
stable snapshot.
