We were updating the files in place. This left a small time frame where files may be commited while in the middle of a write. The final, complete file would then be commited soon after, but we would end up with an ugly, partial commit in the history. Using a temporary file then a rename ensure git only see complete files (rename is atomic on POSIX filesystems).
