obslog: make {patch} not be indented and leave that to the template This removes some unwanted indentation from the tests. In the first case, it's because indent() doesn't indent a blank line. In the second case, it's because we used templating with {patch} and had not requested indentation (but we still got it before this patch). Note that tests will only pass with a very recent Mercurial (one with https://phab.mercurial-scm.org/D7432 applied).
