Thanks a lot for this.

This one would be covered with
GIT_TEST_REBASE_USE_BUILTIN=false. Obviously trivial, but I wonder if
the rest of the coverage would look different when passed through the various GIT_TEST_* options.

That would make it take at least 12x as long if you did them one at a
time. Probably just 2-3x as long in practice since most can be combined
in some way, and somewhat computationally infeasible if you're going to
try all possible combinations.

The fault of a patch I submitted. Couldn't find a sane & portable way to
emulate cases where ferror() would trigger.
