I've tried to narrow it down even further. I cut the test down to just the setup and failing test. Then I removed all "test_when_finished" and replaced the "test_must_fail" with "!" so I can directly copy/paste the test into a window. When the test runs, it fails. When I run it manually, even with using /bin/sh and eval, it succeeds. Can anybody else think of what difference there might be between a shell and the test script that I should test? (I did remember to set GIT_EXEC_PATH and my PATH to run the same version as the script is.)
There's some _very_ weird triggering condition involved here and I'm hoping to narrow it down so I can set some useful breakpoints in gdb and see what's going on inside.

Note: checking out 'HEAD^0'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b new_branch_name
HEAD is now at 1347563... A
