Fix failure to interpret Javascript when autocompleting members for project

  # 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].
