The M_LEADINGSPACE macro was introduced in rev 7.11 of mbuf.h, in August 1988, at the same time as the "new" mbufs, i.e. when external sotrage was introduced, m_act renamed to m_nextpkt, etc. Perhaps the commented code is there to remind what the right thing to do is once you can tell whether or not external storage is writable. I don't think it's reasonable to say that the presence of the comment makes it completely obvious what the intentions of this code were in 1988.
