Turns out that Data.List.Utils.split is slow and makes a lot of allocations. Here's a much simpler single character splitter that behaves the same (even in wacky corner cases) while running in half the time and 75% the allocations. As well as being an optimisation, this helps move toward eliminating use of missingh. (Data.List.Split.splitOn is nearly as slow as Data.List.Utils.split and allocates even more.) I have not benchmarked the effect on git-annex, but would not be surprised to see some parsing of eg, large streams from git commands run twice as fast, and possibly in less memory.
