Oh good, I'm glad it wasn't just me; this was very helpful, thanks.

Aha; this gets to what I was saying in the cover letter, which is that my
patch only fixes the runtime error from perl, and Git.pm happily carries on in
an unsafe directory. Fixing _that_ is probably beyond my knowledge!

If we wanted a test for just the runtime error, something like the following
(including your earlier suggestion to set up the bare repo) demonstrates the
bug and my fix. It doesn't seem like a particularly valuable test on its own,
IMO, but I'm happy to reroll if we want it. Thanks!
