Slava Semushin 6c022798ea Fixed ticket #499 (buffer overflow not detected when using macros)
sprintf() buffer overrun detection works wrong due to typo (since time
when it was added in commit a604f56f19).

Also reports buffer overrun when sprintf() writes bytes equal to
buffer size -- in this case off-by-one error appears.
