It's not just the testsuite though: we do this _all over_ hg itself. For
example, status needs to do something like this:
sys.stdout.write('%(state)s %(path)s\n' % {'state': 'M', 'path':
'some/filesystem/path'})
except we don't know the encoding of the filesystem path (Hi unix!) so we
have to treat the whole thing as opaque bytes. It's even more fun for
'log', becase then it's got localized strings in it as well.
