/**
 * State superclass specialized for whitespace (blank lines & indents).
 *
 * Use this class with `StateMachineWS`.  The transitions 'blank' (for blank
 * lines) and 'indent' (for indented text blocks) are added automatically,
 * before any other transitions.  The transition method `blank()` handles
 * blank lines and `indent()` handles nested indented blocks.  Indented
 * blocks trigger a new state machine to be created by `indent()` and run.
 * The class of the state machine to be created is in `indent_sm`, and the
 * constructor keyword arguments are in the dictionary `indent_sm_kwargs`.
 *
 * The methods `known_indent()` and `firstknown_indent()` are provided for
 * indented blocks where the indent (all lines' and first line's only,
 * respectively) is known to the transition method, along with the attributes
 * `known_indent_sm` and `known_indent_sm_kwargs`.  Neither transition method
 * is triggered automatically.
