clone: call the wrapped function (fixes #181) This is a regression that was brought to my attention in #mercurial: hgsubversion breaks the --update flag. The cause is that we call hg.clone() directly rather than the original wrapped function. A comment in 'wrapper.py' noted that the call to hg.clone() should be kept in sync with 'mercurial/commands.py'. That didn't happen. The original reason for calling hg.clone() directly was that we needed its return values. Another wrapper is added (and cleared) within clone() to get them anyway.
