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

  # Counts the LoC (Lines of Code). Returns an Integer >= 0.
  # 
  # Alias: +loc+
  # 
  # Everything that is not comment, markup, doctype/shebang, or an empty line,
  # is considered to be code.
  # 
  # For example,
  # * HTML files not containing JavaScript have 0 LoC
  # * in a Java class without comments, LoC is the number of non-empty lines
  # 
  # A Scanner class should define the token kinds that are not code in the
  # KINDS_NOT_LOC constant, which defaults to [:comment, :doctype].
