fix: one total and the same words in both modes

Commands break between shell words with a continuation the shell reads,
an option kept with its value. The 40x12 setup and plan keep a note or a
folder whole. Line mode counts files in place and missing, and names the
BIOS folder, as the screen does. The systems question fits its terminal.
