Sounds like a good feature to add. Is this maybe something our terminal abstraction library already supports?

editline does not support bracketed paste. readline, on the other hand, does, along with many other features, such as custom keybindings, vi-mode, etc. Nix already supports being compiled to use readline, but the support for it is somewhat limited. It specifically doesn't support completion right now, although there was a working PR that was rejected several years ago.

Even if Nix didn't swap to readline by default over editline (although I personally think it should), it'd be nice to see some amount of support for it. It's currently treated as a second-class citizen to editline, while providing more functionality.
