The attached patch seems to fix the problem, although it might
be desirable to turn the PREPEND macro into a function.  Feedback
on that would be appreciated.

If we can agree on this approach, then the next step is to use
snprintf("%.0f") to implement "%d" formatting (using a 2nd dynamically
growing buffer for the initial snprintf rendering)...
