Instead of using the working directory, you can also use the `__FILE__`
preprocessor macro to access the files relative to the directory of the
original source file. That at least makes it possible to execute the
result from all directories, but still obviously ties us to the location
of the source directory.
Whether that's ultimately much better.. dunno. But I guess this should
at least be discussed in the commit message.

You can use e.g. "t/helper/test-repository.c" as an example, where we
use `repo_init()` to initialize a local repository variable.
