Lots of code refactoring, simplification and cleanup. Lots of new unit-tests providing much higher code coverage. All courtesy of rillig at netbsd. Other significant changes: o new read-only variable .SHELL which provides the path of the shell used to run scripts (as defined by the .SHELL target). o variable parsing detects more errors. o new debug option -dl: LINT mode, does the equivalent of := for all variable assignments so that file and line number are reported for variable parse errors.
