Maybe it's not absolutely necessary, because the explicit '--split-index' and '-c splitIndex.maxPercentChange=100' would already fully control when index splitting is performed, eliminating any indeterminism inherent to GIT_TEST_SPLIT_INDEX... but unsetting it would reduce the cognitive load on future readers. The same might apply to GIT_TEST_FSMONITOR in the following patch, and perhaps even to GIT_TEST_INDEX_THREADS.
