Prevent empty copy/cut from overwriting paste buffer

[internationils]

When copy-pasting, it can happen that you

• select some text
• ctrl-C (or ctrl-X) it
• switch to a different tab (or somewhere in the same tab)
• click where you want to paste
• accidentally hit ctrl-C instead of CTRL-V

This deletes the paste buffer since nothing is selected. If nothing is selected, ctrl-X/C should not touch the paste buffer.

I've run into this as well, but... I don't think it's wise to break standard copy/paste behavior for our fat fingering. There are legitimate reasons for wanting to clear the clipboard with empty text.

Every other text editor has this same - standard - clipboard behavior.

I'm switching a lot between a laptop keyboard and a full-sized normal keyboard and it's driving me nuts : ) That said, your logic makes sense. An Option might be nice though...
