record: --user/-u now works with record when ui.username not set (issue3857) The -u flag didn't work when ui.username was not set and resulted in an abort message. This was fixed by checking for the 'user' key in the opts dictionary. If the key is present, the step causing the exception is not executed.

parsers: clarify documentation of test-parseindex2.py This change updates and improves the description of test-parseindex2.py. In particular, it removes language that can be interpreted to mean that the test module checks only the C implementation of parsers.parse_index2(). Rather, the module checks parsers.parse_index2(), which can be either the C or pure Python implementation, depending on which version is being used. As of e57c532c3835, the module also does more than just compare the return value with the original Python implementation.
