Btw a question about the new warning: So with
-Wunsafe-buffer-usage-in-libc-call clang now warns on the following?
```
#include <stdio.h>
void foo(void) {
char q[10];
snprintf(q, 10, "%s", "hello");
}
```
It says
```
foo.c:5:3: warning: function 'snprintf' is unsafe
[-Wunsafe-buffer-usage-in-libc-call]
5 | snprintf(q, 10, "%s", "hello");
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
foo.c:5:12: note: buffer pointer and size may not match
5 | snprintf(q, 10, "%s", "hello");
| ^
1 warning generated.
```
Is that as expected? If so, how should snprintf be used to avoid the warning?
