This function splits a bit strangely primarily to avoid changing the behavior of

the test after a bug was fixed with how split/commit --interactive handled

`commands.commit.interactive.unified=0`: when there were no context lines,

it kept only the last diff hunk. When running split, this meant that runsplit

was always recording three commits, one for each diff hunk, in reverse order

(the base commit was the last diff hunk in the file).
