+ * Parse spaces and tabs.
+ *
+ * There is no `nok` parameter:
+ *
+ * *   spaces in markdown are often optional, in which case this factory can be
+ *     used and `ok` will be switched to whether spaces were found or not
+ * *   one line ending or space can be detected with `markdownSpace(code)` right
+ *     before using `factorySpace`
+ *
+ * ###### Examples
+ *
+ * Where `␉` represents a tab (plus how much it expands) and `␠` represents a
+ * single space.
+ *
+ * ```markdown
+ * ␉
+ * ␠␠␠␠
+ * ␉␠
+ * ```
+ *
+ * @param {Effects} effects
+ *   Context.
+ * @param {State} ok
+ *   State switched to when successful.
+ * @param {TokenType} type
+ *   Type (`' \t'`).
+ * @param {number | undefined} [max=Infinity]
+ *   Max (exclusive).
+ * @returns {State}
+ *   Start state.
