In repo controller entry action, show the page for the file even if it's binary (so user still has access to history etc links). This makes it possible to use the entry action as the default when a file is clicked on

  # = Debug Encoder
  #
  # Fast encoder producing simple debug output.
  #
  # It is readable and diff-able and is used for testing.
  #
  # You cannot fully restore the tokens information from the
  # output, because consecutive :space tokens are merged.
  # Use Tokens#dump for caching purposes.
  # 
  # See also: Scanners::Debug
