Other tests make sure that gverify passes. This makes sure that gverify detects
inconsistencies. Since hg-git is ostensibly correct, we artificially create
inconsistencies by placing different Mercurial and Git repos in the right spots.
Unfortunately, these inconsistencies rely on stuff like the file mode,
which we cannot set on Windows.
