In an earlier review, Matthieu pointed out that this test failed to ensure that the 'padright' value did not leak into the next atom. In a subsequent version, you fixed the test to check that condition, but now you've somewhat lost it again, at least visually. That is, because whitespace is "invisible" and because 'padright' now also affects literal strings, someone reading this test can't tell if those trailing |'s in the expected output are padded or not. You could use a different format string to prove that the 'padright' value doesn't leak. For instance:

    %(padright:10)%(refname:short)|%(padright:5)|%(refname:short)

This way, as long as the two |'s are side-by-side, then you've proved that the first one wasn't affected by the preceding 'padright:10'. You could also add back the %(refname:short) at the front of the pattern, as you currently have it, if you want to prove that padding is not enabled at the start of format.
