LibLine: Don't make Editor::load_history() cut off a character per line

Browse source 
For some reason we were not considering the last *two* characters from
the line's ByteBuffer, with the comment next to it talking about \n and
\0. However the buffer doesn't contain a null-byte, so we were
effectively removing the newline and the last character from each
history line!
