Load/save yaml with script. So as to normalize format/style.

No behavior change. Since future changes will be made by scripts,
this separates the more meaningful changes (like adding git url/tags)
from trivial format changes.

require 'yaml'

ARGV.each do |f|
  h = YAML.load_file f
  File.open(f, 'w') do |fd| fd.write YAML.dump(h) end
end
