seems to be failing to init the repo

https://github.com/rustworkshop/gitopolis/blob/d012fe8f2bc2e787fcf9f1fbc24ef14220a9455f/tests/end_to_end_tests.rs#L757-L761

while debugging, after that step:

                          separate git dir from working tree

hmm, so why did the test not fail obviously at that point?

extra param added in 0f04944 and modified in d012fe8

[timabell]

time to switch to libgit or something instead of shelling out for tests?
