[Dev-luatex] luatex 0.79.1 does not log \openout calls

Compiling this source: Hello\immediate\openout3=myfile.txt\relax\bye with pdftex generates a log file containing: \openout3 = `myfile.txt'. Compilation with luatex does not. Compare the attached log files. Some scripts (like latexmk and texi2dvi) depend on such log entries for the detection of auxiliary files and they therefore don't co-operate properly with lua(la)tex. -- Wybo
