was very helpful for developers but may annoying users.

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.

Kimmo Varis 70db2562f4 Fix ticket #417 (Crashes in Windows because of invalid char value)
8-bit characters and UTF-8 characters are now converted to spaces. They can only appear in the code files in comments or string/char constants. So we cannot just ignore them as that would change length.
