old backups of excluded files?

What happens to backup copies when I exclude files later? I could exclude by
[list]
[] removing from folder tree
[
] placing in the file exclusion list
[*] placing in the folder exclusion list
[/list]
Note that I am not talking about deleting the file from disk, just about the CBB configuration.

It might be
[list]
[] removed from backups on next run
[
] not updated but left for potential restore
[*] left in the backup but not available for restore
[/list]
Thanks,

Edward
