i think there's an unexplained twist in the logic.  byron's rc is a non
sequitor.  rc (the real one from p9p) could be made to run on all the go platforms,
and would be uniform across them all.  one suspects therefore that
the reason is either that rc doesn't run on all the platforms, or that
the go team thinks rc is not preferrable.  for example it could be
that the thought is that rc might distract from the real point here,
go.

i don't know.  but the problem isn't the consistency of rc.  byron's
rc doesn't count.  that's like saying the bourne shell is not consistent
because of bash.
