Log Message:
Improvements to hat-explore.
  * Use a different low-level interface which gives correct parent
    information for identifiers, constructors, and literals.
  * In the state, store a stack of sub-expression contexts, not just
    expressions.  Thus, when you go backwards up the display, the cursor
    returns to the previously selected subexpression, not the whole line.
