Evaluation goes past cursor

[spaanse]

Take the following incomplete proof (the | marking my cursor)

Lemma nat_not_negative : forall i : nat, ~(i < 0) .
Proof.
   intro i. |
Qed.

Note the space between the . and my cursor. If you then instruct the plugin to evaluate to the cursor it will also evaluate the Qed, and then complains the proof is incomplete. This seems to be caused by the fact that the evaluate to cursor doesn't consider where the check will end up after evaluating one extra statement, instead it just checks if we are still before the cursor. So unless the cursor is right after the . it will always evaluate an extra statement.

Suggestion for a fix:

- if manager.autorun_forward and manager.position < manager.autorun_point:
+ if manager.autorun_forward and self._find_statement().end() < manager.autorun_point:
