Yeah, the behaviour of *printf is weird in this respect (and that of
Extlib's printf is even a tad worse). For this reason, in Batteries
Included, we have 
 Printf.sprintf  (which behaves as the base Printf.sprintf)
and
 Printf.sprintf2 (which behaves as you expected)

All of this in addition to our [Print] module, which offers a syntax
comparable with [Printf], but allows extending the format rather than
using %a and %t.

Cheers,
 David
