Belay that.  Here's what's in the SpamBayes source:

    scale = options["Tokenizer", "ocrad_scale"] or 1
    charset = options["Tokenizer", "ocrad_charset"]
    ...
    ocr = os.popen("ocrad -s %s -c %s -x %s -f %s 2>/dev/null" %
                   (scale, charset, orf, pnmfile))

So I already allow the user to adjust the scaling factor and properly use
the -s flag.  I think the incorrect usage was confined to my postings.
