Description

It may be easier to identify what causes error commands to be returned on an exec if the command is included in the error message. this can be done with

• a toString() operator on the class that includes the list of arguments (when non null)
• a test that this works with arguments with spaces, and a null array
• relevant use of the operator when an execute fails, such as in TaskTracker
