Ulf,

Since ~2 weeks there is tremendous amount of trivial patches coming from
vivo.com. I identified at least 6 buggy, where the contributor did not
understand the code. Not sure about intention, but I advise extra
carefulness when dealing with these "trivial" improvements (because we
tend to apply things which look trivial).

Best regards,
Krzysztof
