    Do not omit the starting space when copying (#9995)
    
    The offending code appears to have been introduced a long time ago. My
    understanding is that it is no longer relevant. Notably, it only appears on 
copy
    and not on cut, which tells us that: 1) it should be safe to remove it, 2) 
we
    should remove it for consistency.
