Yes, you have to move them.  But it's no big deal.  Here's your tool:

#! /bin/sh
#
# shrinkdir: shrink oversized directory files.

PROG=shrinkdir

for i in $*
do
	if [ ! -d "$i" ] ; then
		echo "$PROG: $i is not a directory."
		continue
	fi
	mkdir $i.tmp$$
	if [ $? -ne 0 ] ; then
		echo "$PROG: couldn't make temporary directory; $i not shrunk."
		continue
	fi
	mv $i/* $i/.[!.]* $i.tmp$$
	if [ $? -ne 0 ] ; then
		echo "$PROG: couldn't empty $i; $i not shrunk."
		mv $i.tmp$$/* $i.tmp$$/.[!.]* $i 2>/dev/null
		rmdir $i.tmp$$
		continue
	fi
	rmdir $i
	if [ $? -ne 0 ] ; then
		echo "$PROG: $i not replaced; contents left in $i.tmp$$"
		continue
	fi
	mv $i.tmp$$ `basename $i .tmp$$`
done
