A lot of files that are not the main test scripts had no

line number from a failure/exception message.

Along the way, some are lightly reformatted and some add a
DefaultEnvironment call.

* Reformat some stuff.
* Some linting and commenting in Jar tool.
* Enabled test for a non-java file when Jar source is a directory
  (was commented out) - needed to add a Command to copy the file
  to the directory where the class files were generated.
