xine plugin uses it, but expects it to return title time. Most titles
use only single clip so I haven't noticed this before.

API documentation just says "return current time", maybe that could be
clarified too.

If you don't want to break API, you can always add something like
bd_tell_title_time() { return bd_tell_time() + clip->in_time; }

But if it is bug, fixing it does not break API :)
