  Log:
    webrick/httputils: note Kernel#open behavior
    
    I don't know who uses the load_mime_types method; but it is
    conceivable that a user would want to read the results of a
    command instead of reading a regular file to load MIME types.
    
    None of the WEBrick-related code in Ruby or default/bundled gems
    seems to rely on this method; but it is likely 3rd-party code does.
    
    * lib/webrick/httputils.rb (load_mime_types): note Kernel#open behavior
