annotate tests/logexceptions.py @ 36747:4c71a26a4009

sslutil: some more forcebytes() on some exception messages At this point, test-https.t no longer dumps tracebacks everywhere. Instead, we get some results that look like we're not adequately finding things in hg's configuration, which should be manageable (if somewhat annoying to find and fix.)
