I scanned through the implementation of snprintf several times 
while I wrote the replacement.  I think, the main algorithm is 
quite similar, apart from some speed improvement for numbers 
close to zero, which turned out to be quite nasty in detail (and 
which for now I skipped therefore).

By the way: A 1 to 1 translation would not be something, I could 
do, because my knowledge of C is very little and the algorithm 
contains lot's of calls to functions I do not know, where to look 
them up and how to replace them with D functions.
