Log Message:
make(1): describe how Parse_Error might print stack traces

In deeply nested include chains and .for loops this may be a useful
feature.  It's a little tricky to generate an intuitive stack trace,
though not impossible.  This explanation also serves as a detailed
documentation about how the .include and .for directives are
implemented.
