Bug report

What happened

p command is yet not Vim compatible behavior.
For example, the buffer content is:

hello
world

And cursor position is line 1, then type ddVpP results in:

world
hello

Unnecessary newline is left at the beginning.

What did you expect to happen

Expected result is (no newline at the beginning):

world
hello
