A useful thing to be a test on the number of non-structural entries in a directory.
By non structural, it would work like ls -A, and not include entries that are
part of the directory structure like "." and ".." -- with the idea of being able to quickly determine if a directory is empty. Maybe 'inodes' with standard +/- adjectives So "find . -type d -inodes 0" would find all the empty dirs. Unless, of course this is already in there and I've missed it... but didn't see anything that would provide this w/o calling an external func on each dir...which really slows things down...
