It's safe if done right. It's just easy to mess it up.

I though pointer arithmetic was faster - but I guess with todays
optimizing compilers it won't make a difference.

The function converts '|' chars into \0 chars. The string itself
contains two || at the end. The function doesn't have to check or even
do it (it can't really do it - appending isn't allowed because that
would cause a buffer overflow).
