I don't think it's a right thing to do, as it doesn't obey nor SHAREOWN/
SHAREGROUP not SHAREMODE, which all ports are supposed to follow. Exactly
for these reason we have special macros COPYTREE_* in bsd.port.mk. Any
chance emacs port could be tricked to use these macros instead of a hand-
crafted untar command?
