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)
