CI running times naturally add up over time as more and more stuff is
tested. That's why I would argue testing GIT_TEST_SPLIT_INDEX on 64-bit
is probably sufficient. However, I am not really familiar with
GIT_TEST_SPLIT_INDEX.
There is no right or wrong here and either way is fine with me.
I just wanted to express my "keep an eye on CI time" concern.
Thanks,
Lars
