The preprocess mention is great - because now I can propose an addition to fix what had bugged me about 914's current implementation of the min/maxdepth behaviour: the fact that the files have to be looked at, and if for no other other reason than to discard them. preprocess lets one avoid that:

sub prep {
    my $depth = $File::Find::dir =~ tr[/][];
    return if $depth > $max_depth;
    return grep -d "$File::Find::dir/$_", @_ if $depth < $min_depth;
    @_;
}

This way, in directories below the mindepth, nothing other than directories is even looked at. Also further recursing down the current branch of three directory tree is aborted immediately upon entering a directory deeper than maxdepth.

The mindepth test in wanted() is still necessary because the directories below mindepth will have to be processed; the maxdepth test there is superfluous.

Makeshifts last the longest.
