It's not exactly prose, but the error message is correct. It says:

The D#2 version is translated from C, the D#3 comes mostly from C#.

I may send this D2 version to the original author...

No, I agree. I think for the sake of templating, improving the error
message is the best option - probably #3 (special case error message) imho.
