Looking at it a bit more closely I wonder if it could be done more
efficiently. Is it possible to scan from the back of the buffer until
mbrtowc returns n > 0, then trim the buffer to current_pos + n? Or am
I missing some tricky multibyte issue? Seems a bit nicer than walking
over every character of every line.
