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.

# Tests for the :_ modifier, which saves the current variable value

# In the parameterized form, having the variable name on the right side of
|
|
# the = assignment operator is confusing. In almost all other situations
|
|
# the variable name is on the left-hand side of the = operator. Luckily
|
|
# this modifier is only rarely needed.
