normalize the ordering of tame requests (particularily, "rpath wpath cpath",
which i have put in that order). this is not important, but helps look
for outliers which might be strange.  it hints that "ioctl" should be
reassessed in a few places, to see if "tty" is better; that "unix" may
be used in some places where "route" could now work.
