OK, by coincidence I just booted a new computer with Windows 10, so I installed
the PSPad dev version you mentioned, recreated the file:|

cite:
--------------------------------------------------------------------------------
123456789-123456789-
abc--------------------------------------------------------------------------------


set the soft-wrap at char 10, selected "abc", clicked Edit > Lines
Manipulation... > Swap with line above, and got this:

--------------------------------------------------------------------------------
123456789-
123456789-[soft-return]
123456789---------------------------------------------------------------------------------


I can't imagine why it works for you, and not for me. Maybe I'm not explaining
it clearly enough. 

At least there's a solution: Undo + turn off wrap-lines + do it again.
