    Fix extra bracketed paste markers when pasting >8kb
    
    Before this patch, when pasting over BUFSIZE (8192 bytes here), st would
    do the following:
    
        \e[200~...8192 bytes...\e[201~\e[200~...remaining bytes...\e[201~
    
    With this patch, the start marker is only sent when the offset is 0 (at
    the beginning of selnotify) and the end marker is only sent when the
    remaining bytes to read are 0 (at the end).
    
    For short pastes, both conditions are true in the same iteration.
    
    For long pastes, it removes the extra markers in the middle, keeping the
    intended wrapping:
    
        \e[200~...8192 bytes......remaining bytes...\e[201~
