- Rename the test repo to match the test function so we can create
more test repositories for other tests at a later stage.
- Remove useless hooks and configs from the repo (they are not used
for our specific test and just need memory).
- Note the fix for issue 721 in NEWS.mdtext.
The SVN backend failed when trying to access historical information on deleted files.
There's also an initial test case for the SVN backend, testing this issue
and issue 364, which is about a similar problem for renamed files.
Reverting any of these fixes breaks the test.
