[tor-commits] [stem/master] Doc example unit tests used relative paths



commit 63c08cc70c69776e55197d0a9b6bb86d6b644c6b
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>

    Doc example unit tests used relative paths
    
    Recently we changed our unit tests for tutorial examples to test the docs
    rather than a copy of the code (yay, no more duplication!). However, we used
    relative paths so our unit tests failed if executed outside of our base stem
    directory. Caught by toralf.
