Thanks for the suggestion. How about the following patch instead?
I tried to tighten up the wording a bit.

+The ISO C99 standard says that if the output array isn't big enough and if
+no other errors occur, @code{snprintf} and @code{vsnprintf} truncate the
+output and return the number of bytes that ought to have been produced.
+Some older systems return the truncated length (e.g., GNU C Library
+2.0.x or IRIX 6.5), some a negative value (e.g., earlier GNU C Library),
+and some the buffer length without truncation (e.g., Solaris 7).
