I think we should forget about invoking rm as a subprocess at all, and
just do the recursive directory walk and unlinks for ourselves.  We
already have code to do this for copy in copydir.c, and unlink would not
be any longer.  We will probably be forced into implementing database
removal for ourselves rather than by 'rm' hacks anyway as soon as
tablespaces come to pass; so why contort initdb's behavior for a very
transient implementation savings?
