[Pw_forum] two program logic questions in TDDFPT

[Simon Binnie]

Thanks. You are right about the duplicated zcopy line, it is rather  
pointless to perform the same copy twice in a row. It's not necessary to  
copy sevc1_new though as far as I can see, since this is only really used  
as a workspace within lr_apply_liovillian. The only thing that is  
important is to make sure that evc1_new gets copied so evc1_old can then  
be properly updated.

Best regards,

Simon
