example02 always reports -F in the history

$ ../build/Darwin/test/example02 ../build/Darwin/test/Ntuple01/0.root test.root -c test/example.info
...
$ printMetaInfo test.root history
parallel /home/louis/Documents/Darwin/Installer/build/Darwin/test/Ntuple01/example01 Ntuple01/ true 4 2016 AK CHS HIPM -j 2 -f

    -s -F

(Formatted for readability.) The -F in the history is not present in the command line options.

The output tree is empty so printFriends does not work.
