Do note that -size on directories is filesystem dependent.
I.e. on ext2+ it's the number of bytes allocated to directory structure, in
multiplies of whole blocks.

Just as predicted.
If you want to find files, search for files.
find . -type f ...

Having something to this extent would be useful in case of searching for
directories with too many files, for example.
I'd vote for something like (entries << 7), which is closer to an average ext2
counter. No need to ignore anything.
