tests-subrepo-git: emit a different "pwned" message based on the test

Having a single "pwned" message which may or may not be emitted during the
tests for CVE-2016-3068 leads to extra confusion.  Allow each test to emit
a more detailed message based on what the expectations are.

In both cases, we expect a version of git which has had the vulnerability
plugged, as well as a version of mercurial which also knows about
GIT_ALLOW_PROTOCOL.  For the first test, we make sure GIT_ALLOW_PROTOCOL is
unset, meaning that the ext-protocol subrepo should be ignored; if it
isn't, there's either a problem with mercurial or the installed copy of
git.

For the second test, we explicitly allow ext-protocol subrepos, which means
that the subrepo will be accessed and a message emitted confirming that
this was, in fact, our intention.

    This tests for edge cases in url.URL's parsing algorithm. Most of
    these aren't useful for documentation purposes, so they aren't
    part of the class's doc tests.

    Query strings and fragments:

    >>> url('http://host/a?b#c')
    <url scheme: 'http', host: 'host', path: 'a', query: 'b', fragment: 'c'>
    >>> url('http://host/a?')
    <url scheme: 'http', host: 'host', path: 'a'>

    >>> url('http://host/?a#b', parsequery=False, parsefragment=False)
    <url scheme: 'http', host: 'host', path: '?a#b'>

    IPv6 addresses:
