    cgram(6): Don't move over the last char and fix an assertion
    
    The maximum value of cursor_x was the text length and thus also
    *equaled* to extent_x, which broke the assertion in substitute()
    and caused crashes.
    
    In addition, the cursor could move just beyond the last character
    on a line, which didn't make much sense.
    
    So only allow the cursor move to the last char but not over it.
    This also properly fix the above assertion issue.
