tests: handle .t files without trailing LF 9a2de8dae27b made this simple test-test.t succeed silently: $ printf ' $ true' > test-test.t but did not give a usable .err in this case: $ printf ' $ false' > test-test.t The missing LF will now be fixed in the test output and it will thus give a test failure and a solution in the .err file.
