--delete and --files-from

I want to maintain mirror of a sliding window of the last N
subdirectories of a particular directory. My first attempt was to use
ls -t|head to generate a list of dirs to pass to --files-from (with --
recursive). It's working nicely to add the new files to the mirror
each day, but --delete isn't removing the old files (which are now
which are now outside the window and not in the --files-from file).

My guess is that the subdirectories of the target directory not
mentioned in the --files-from file are not considered part of the sync
and are thus not considered for deletion. (Whereas if there were files
in directory inside the window that were present only on the remote
end, they *would* be deleted.) Am I correct in this analysis? How
would you suggest I fix this?
