[PATCH 0/5] cex: display the rule numbers

This is a bit exploratory, I'm not sure about the format.  The point
is to include the rule numbers in the counterexamples.  I'd be happy
to read comments about this.

From

    Example: "if" expr "then" "if" expr "then" stmt • "else" stmt
    Shift derivation
      if_stmt
      ↳ "if" expr "then" stmt
                         ↳ if_stmt
                           ↳ "if" expr "then" stmt • "else" stmt
    Reduce derivation
      if_stmt
      ↳ "if" expr "then" stmt                        "else" stmt
                         ↳ if_stmt
                           ↳ "if" expr "then" stmt •
