Preserve line current length in Duplicate and Shift

Browse source 
It's quite rare to actually want a multi-frame line followed by a
single-frame line; in most cases they're either all a single frame (in
which case this behaves the same as it always has), or they're all
multi-line, in which case this should be more convenient.
