The bigger issue with the early printf is it just

There was a comment in the manual that the fout concept was kludgy.
V6 'iolib' printf has an interesting approach to fixing this:
If the first argument was 0 through 9, it was taken to be a file descriptor, and the
second argument was the format string. If it was -1, the second argument was the output
string (as for later sprintf), and the third was the format string. Otherwise, the first
argument was the format string.
(I'm curious as to how much "iolib" was actually used, since it
doesn't appear to have been included by default - there was a different printf
routine in libc)
