Instead of having detailed error messages, run most commands through a function that calls err() under fault conditions. Where detail is still required, err() is still called manually. Where it isn't, the error message is simply whatever command was executed to cause the error. This results in a massive sloccount reduction for lbmk; specifically, 178 sloc reduction, or a 8.1% reduction. The total sloccount is now 2022, for shell scripts.
