[O] Kill all items with specific tag to kill-ring.

[Oleksandr Gavenko]

I use tags only on top level items in org-file.

And want move all items marked by specific tag to different org-file.

I expect that this command kill items with selected tag to kill-ring in one
step (so single undo command return original buffer content).

Seems there are no such command build-in command...
