bug#12675: find RFE test verb "-inodes"

[Linda Walsh]

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...
