**/* recursive glob: any file in current directory and  below.
(ND/^F): glob qualifier: modify glob behaviour and further
filter files based on other attributes than name:
N: don't fail and don't expand to anything if there's no match
(nullglob)
D: include dot files and descend into dot dirs (don't ignore
hidden files).
/: select only files of type directory
^F: directories that are /not-full/. a "full" directory here is
one that contains at least one entry other than . and ..

Do **/*(ND/^F) is the list of empty directories (recursively).
