Loosely related, find files when they are not in tests directory is less than ideal:

> library(unitizer)
> unitize('empt')

| unitizer for: ../empty.R                                                     |

Note the ../empty.R when that file is actually in the working directory.

We're not going to worry about the '../empty.R' issue.
