Normally this command will produce a SORRY event if it is executed while a
drive is aquired. One may override this ban by prepending the character "+"
to the argument of -file_name_limit.
If -file_name_limit is executed while an ISO tree is present, the file names
in the ISO tree get checked for existing truncated file names of the current
limit and for name collisions between newly truncated files and existing files.
In both cases, the setting will be refused with a SORRY event.

One may lift this ban by prepending the character "+" to the argument

invalidating their MD5 part. Colliding truncated names are made unique,
