Change Details

The following three function calls correctly return an error that the pattern has an unclosed capture: ``` require('ustring').find('abcdefghi', '(abc)(def)(ghi') mw.ustring.find('abcdefghi', '(abc)(def)(ghi') mw.ustring.find('abcdefgh', '(abc)(def)(ghi') ``` However, the following one gives no error and instead just returns nil: ``` require('ustring').find('abcdefgh', '(abc)(def)(ghi') ``` It should return the same error as the other three.
