My original message is not quoted enough in detail here to see the
difference. But there is a difference:
CHROOTDIR == /usr/obj/${.CURDIR}/tmp != /usr/obj/${.CURDIR}
The above sub-optimization only rapidly deletes the chroot tool dir, aka
/usr/obj/${.CURDIR}/tmp, not /usr/obj/${.CURDIR}.
This is the second person to make this mistake, so don't feel bad.
Another side effect of my ``fix'' is it restores the intended behavior
by the original author of ``make cleandir''. The current code will
leave things behind in /usr/obj if a node of the tree is removed as
it depends on the tree traversal to clean things up, and if the node
is no longer traversed into it will remain in /usr/obj/ until someone
manually cleans it out.
