docstring: Print (to stderr) a warning message tied to the current logical
             line in the current file.  If the current logical line in the
             file spans multiple physical lines, the warning refers to the
             whole range, eg. "lines 3-5".  If 'line' supplied, it overrides
             the current line number; it may be a list or tuple to indicate a
             range of physical lines, or an integer for a single physical
             line.
