Sounds good. I am interested in reports of excessive false positives so please
let me know if you run into some.
FYI: I'm testing a patch that splits out the snprintf truncation warning from
-Wformat-length and adds a new option (-Wformat-truncation=n) to control the
former independently of the latter. Under this patch, the "may be truncated"
warnings are issued at n=1 when the snprintf return value is unused, and only
at n=2 when it is used. I'll post it for review sometime this week.
