Reinstate the (apparently) load-bearing empty bracketed paste#20037
Conversation
Some applications have come to rely on an "empty" bracketed paste packet to indicate that the clipboard was _requested,_ but not sent. Some agentic CLI tools use this to guess whether the clipboard contained e.g. an image or otherwise unserializable data. Apparently, gnome-terminal and VS Code do this; others as well (I tested xterm, konsole, gnome-terminal and I can't remember which ones did and which ones did not.) Refs #19517

this will act just as squirrely as pasting in broadcast already does, so, whatever. I'll fix it in post.

I probably broke it when I rewrote it pasting to use Win32 APIs huh? I bet I added the early return then. |
