I just needed to go outside the current test git directory, the tests

Even if you mean to use "cd",
please do so within a sub-shell.

I thought about it, but clearly all the tests are run in a sub-shell, so
it didn't seem necessary? But happy to change, I don't really care
either way.

Please learn to care before you write your next test, then ;-)

Hey now, I'm fixing your segfaults ;-)

These tests are not run in a sub-shell; they are eval'ed, so that
the assignment they make to variables can persist and affect the
next test piece.

Makes sense. FWIW, the test *did* restore the CWD so things worked, and
subshells are actually ugly (need to import test-lib-functions.sh again
if you want to use those), but I'll make it work somehow.


More importantly, how do you feel about the "cd /"?

The tests are always run in a place where there's a parent git folder
(even if it's git itself), so you cannot reproduce the segfault in a
test without the "cd /", though I guess "cd /tmp" would also work or
something, but "cd /" felt pretty safe, hopefully not many people have
"/.git" on their system.
