Set the $$< automatic variable as best we can during secondary expansion of prerequisites. * src/commands.c (set_file_variables): Don't break without setting 'less' if secondary expansion is enabled. * tests/scripts/features/se_explicit: Test secondary expansion results. * tests/scripts/features/se_implicit: Test secondary expansion results.
