This prevents the TestBot and test.winehq.org from recognizing test 
failures when there's a context string. The Testbot expects

   [_a-z0-9]+\.c:\d+:[0-9.]* Test failed:

But it gets lines like this instead:

registry.c:4104: L"Bahia Standard Time": Test failed: expected L"Bahia Daylight Time", got L"Bahia (heure d'\00e9t\00e9)"

Ideally the context would go after "Test failed:". Otherwise that means 
allowing anything in between the file+line and "Test failed:" which 
increases the risk of allowing bad matches.

Note: Same goes for "Test succeeded inside todo block", "Test 
      marked todo", etc.
