Stripping the humongous Cc list for sanity.

Hoping? Nah, thanks.

Ulrich's example already _has_ a variable that is then changed from 
const char * to const char[]. Of course doing that will save you the 
extra pointer.

But vsprintf.c on the other hand did not have that extra variable to 
begin with! But it is ok nevertheless, and the unification of <NULL> vs 
(null) is worthwhile.
