Create failing test, address #278

[neagle]

Thanks for giving me the green light to create a pull request. After running my suggested fix through the test suite, I'm no longer sure what the right way to fix this is: my suggestion breaks some other cases.

Instead, I created a test that fails when given the conditions I described in my issue. Hopefully this makes things as clear as possible so that someone with more experience on the project than I have can suggest something.

Please let me know what else I can supply from my end: I'd definitely like to do whatever possible to help fix the problem for my use-case.

Moved your tests in by hand. Had to update neagle@4690842#diff-e5b8495db5b34b144973178386ba5ceeR426 because it was producing the wrong file name for the subdirectory file
