-Subject: [PATCH 2/2] tinystdio: Fix snprintf(buf, 0, ...) to not smash buffer
-
-snprintf(buf, 0) should not write anything to the destination, not
-even a trailing '\0'. The tinystdio implementation had a signed
-comparison bug where this case would cause a null to be placed in the
-output buffer at the size of the data that would have been written.
-
-Add a test to make sure snprintf respects the 'len' parameter
-correctly.
