PMS does not mention that diropts should be respected when dodoc -r
creates directories recursively. This is consistent with the behaviour
for regular files, where insopts isn't respected either.

A parallel patch for further clarification of the PMS wording has been
sent to the gentoo-pms mailing list for review.
