MT#61856 main: prevent duplicated usage of `F` shortcut

Already used by `--no-fallback`, so the rest just probably
inherited the same letter when doing copy-paste.

That is ambiguous and may cause option parsing conflicts.
Keep `F` only for the historical(most important) option
and set the rest to 0.
