## The Problem

werkcrappit's PR#44 had a section "Open Questions" with the single paragraph `None.`;
werkrevisor counted that paragraph as an open question and gave RED.
An author who states that there are none should not have to delete the section to pass.

## Non-Goals

- No other wording than a plain "none" counts as empty; "None so far, but …" stays an open question.
- No change to items with checkboxes or to deferred `TODO.<topic>:` items.

## The Scenarios

### Feature: a section that states "none" has no open questions

#### Scenario#42.01: a paragraph "None." is no open question

So that an author can state explicitly that nothing is open.

- **Given** a PR document whose section "Open Questions" holds only the paragraph `None.`
- **When** werkrevisor checks the open questions
- **Then** it finds none

##### Verified by

- [test_open_questions.OpenQuestionParserTest.test_a_none_paragraph_is_no_open_question](../../tests/test_open_questions.py)

#### Scenario#42.02: a list item "None." is no open question

So that the same statement as a list item passes too.

- **Given** a PR document whose section "Open Questions" holds only the item `- None.`
- **When** werkrevisor checks the open questions
- **Then** it finds none

##### Verified by

- [test_open_questions.OpenQuestionParserTest.test_a_none_item_is_no_open_question](../../tests/test_open_questions.py)

#### Scenario#42.03: a sentence that starts with "None" stays an open question

So that a real question cannot hide behind the word.

- **Given** a section "Open Questions" with the paragraph `None so far, but who decides the limit?`
- **When** werkrevisor checks the open questions
- **Then** it finds this paragraph as an open question

## The Solution

- `specdocs.open_questions` skips a paragraph or list item whose whole text is "None" or "Keine", with or without a final full stop, in any case.
- `docs/prs/README.md` names the rule.
