It was backported to 2.2-stable ages ago...  It is rev 1.7 in 3.0-current 
and 1.3.4.1 in 2.2.

Be careful.. If it's the version I'm thinking of, I wouldn't be so quick 
to do this.  One version I've seen around scans for % fields in the string 
to estimate the size and does a malloc and vsprintf.  This scares the hell 
out of me...

You can get the current 2.2 version and it should just drop into both 2.1
.x and 2.2.[12].
