With long options one can't stick something that takes an argument
in the middle of a bunch of others (which was the error I thought
was present here, and would have been the case if your example had
the options in the same order).
It's also more readily apparent what the options do, though that's
not much of an issue for common things like tar or rm. I for one can
never recall if it's -c or -C that's --reuse-message for git commit.
