maybe, but as Wolfgang points out, the whole point of unifying these code 
paths was to shrink code.  re-expanding it just so that the printf is clear is 
not worthwhile imo.  personally (and probably since i'm the one who changed 
the 3xprintf into 1 printf) find the field width version easier to understand.
