I reached a similar conclusion when I looked at it this morning.
We could make the code marginally better in the sense that we'd
remove the static buffer, but at the cost of making the code
a little more convoluted (once we malloc, we need to make sure
we always free, which probably means a cleanup, etc). So I also
vote for leaving the code as is.

That lead me to consider the removal of this rule.  But in the end,
I think it's useful to be reminded every time we use sprintf that
there is xtrsprintf. Since this hasn't produced too many false
positives, I think it's OK to keep it for now.

In the meantime, I think there is a way to say that this line is OK.
If you put /* ARI: sprintf */ on the sprintf line, that should take
care of the warning...
