}  Um, I can't imagine this being true for *any* remotely normal flavor of Unix.

You're right Jon [ :-( gasp!, did I really say that? ]
But why are you all making this so hard?????
Its easy. 
do this:
---isempty---
#!/bin/sh
dir=$1
num1=`ls -aF $dir | grep -v "/$" | wc -l`
num2=`expr \`ls -lad $dir | cut -c12-13\` - 2 `
num=`expr $num1 + $num2`
if [ $num = "0" ]
then
   echo The directory is empty
else
   echo The directory is not empty
fi
---isempty---

then just do
isempty directory_in_question
and it will tell you if the dir is empty or not
