It would be a different story if the caller does not necessarily have a ready access to the_repository, but it is a global, so the caller can pass the_repository and be more explicit. Giving two ways to the caller to express same thing is not a good idea. Thanks.
To be fair, I added several "if (!r) r = the_repository;" statements to the original public FSMonitor routines. There were obscure cases where tests would sometimes randomly fail because "r" wasn't completely passed down via some hard to isolate call stack. Offlist, AEvar told me that he managed to isolate it and has a fix. So eventually, we'll be able to get rid of all of these direct references to "the_repository" and properly assume that "r" is always passed down. But for now, I think we should let this stay for safety. Jeff
