Is pkg now ready to reference-count multiple packages referencing the
same directory?

I strongly object to this part, and request that such dead code not be
added to pkg.  This is a gratuitious change, for "vendors" that as of
now are phantoms (lack a particular use case), and, as written before,
it voids error checking on the file type, and dead code is usually
buggier than used code because noone sees the bugs until the code is
enabled (but not properly reintegrated) years later.

The use case why we need the distinction is the common error
if a maintainer forgets the mkdir in the {pre,do,post}-install: target,
and the install path lacks the trailing slash, then packaging will no
longer fail.

Example:

post-install:
	${INSTALL_DATA} blah/something ${STAGEDIR}${DOCSDIR}/blah

This will rename something to blah while installing into ${DOCSDIR},
rather than installing "something" into ${DOCSDIR}/blah/.

Especially with make makeplist or auto-plist rigs, this is bound to
fail, and sit undiscovered for a while.

If the distinction between directory and other file types remains
explicit and mandatory, these errors are much harder to find.
