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.

Mercurial's default format for showing changes between two versions of
a file is compatible with the unified format of GNU diff, which can be
used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the
following information:
- executable status and other permission bits
- copy or rename information
- changes in binary files
- creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS
which addresses these limitations. The git diff format is not produced
by default because a few widespread tools still do not understand this
format.
This means that when generating diffs from a Mercurial repository
(e.g. with :hg:`export`), you should be careful about things like file
copies and renames or other things mentioned above, because when
applying a standard diff to a different repository, this extra
information is lost. Mercurial's internal operations (like push and
pull) are not affected by this, because they use an internal binary
format for communicating changes.
To make Mercurial produce the git extended diff format, use the --git
option available for many commands, or set 'git = True' in the [diff]
section of your configuration file. You do not need to set this option
when importing diffs in this format or using them in the mq extension.
