I am looking into resolving dtolnay/anyhow#55 and this looks like one of only 2 places on crates.io where "{}" is used intentionally in an error message — meanwhile there were a couple dozen where it's a bug where they forgot to pass a second argument that was supposed to be interpolated in the message.
If you are open to tweaking this code, I'll land a fix for dtolnay/anyhow#55 to help others catch missed format arguments.
