Hard links to directories: why not?

Because the (4.3)BSD "ln" command doesn't seem to, either:

	auspex% cp /home/unix_src/bsd4.3/bin/ln.c .
	auspex% cc -o ln ln.c
	auspex% echo >foo
	auspex% echo >bar
	auspex% ./ln -f foo bar
	bar: File exists

and because the command sequence

	rm -f bar && ln -f foo bar

for example, would have done the job quite nicely....
