    Fix crash found by vttest. · 3dfa12a6
    Deucе authored
    If DL was passed a parameter equal to or greater than the number of
    lines from the current line to the last line in the region, it would
    try to move a negative-sized box up, which resulted in a crash.
    
    This fixes that three ways:
    1) Do not allow moving boxes with negative X/Y sizes
    2) In dellines, clamp the lines to the number that could be deleted
    3) Don't move lines up of all rest of the lines are being deleted
